I’ve been running the ppm down from 500 to 400 during last week, & running around 300 in the fresh res now. Plant started showing calcium deficiency last week, so I bumped that up a little this week, & enough ArmorSi to counter the N in the calimagic with some more K. Nute ratio for the 3-part is the final one from the factory chart. Been trimming away leaves as they yellow. Added another guywire to one of the buds to move it over. Some of the calyx are starting to purp out, & I keep finding ones in my pics that look like bud rot, so I go check them, & so far they have just been purple & not rotting.
Thermpro of last week: Mostly cooler & humid/ raining out. Today was nicer, but the next few days are supposed to be cool & damp/raining again. Was thinking of turning on the heaters to get the transpiration higher, but decided against it since the plants haven’t felt the heaters before, & I figured that it might cause more issues than cold leaves & high RH. They are still moving about 1/2 gallon a day despite the conditions. Keeping an eye out for wpm.
Still have some foxtails developing, but they are not too bad & don’t seem to be growing quickly. I think that they have more to do with me needing to continue to dial in my nute mix across flowering, & maybe from the occasional pH crashes & general ambient conditions (RH swings), rather than too much light, at least not at this point, but I raised the light up another click anyway, & I also started checking the trichs. Hoping for them to be ready within the next week or two.
About 36 hours after hanging everything, I went in & pruned & re-strung some of the buds from the candelabra-shaped stalks, since they were making me a little nervous in terms of mold:
Still in veg, hoping to flip soon. Did some training to spread them out & to get the shoots heading back up to the screen. I’ll probably flip before they hit the screen, & I’ll just let them grow through this time. Will be more of an LST growing through a screen rather than a SCROG. Just want to get things moving along a little more quickly if possible, for the next couple rounds.
Picked up some heat from the Photontek after activating it at around 6:30 yesterday. See The Kind at 50% power (~110w) before & the P’tek at 50% power (~150w) after. Also I activated the plate-heater controller a few days ago, & it has been operating mostly during lights-out (2am thru 2pm):
Running around 550 ppfd, 600ppm, 6.2 pH. Haven’t checked the leaf temp offset yet since switching the light, but it usually spreads a little with the Photontek vs. the Kind. It had been running around -8 with the Kind, & I wouldn’t be surprised if it grows to around -10 or -12 with the P’tek. Probably mostly to do with the greater distance between the plant & the canopy.
Trimmed & jarred the last haul. Ended up with around 6.5 oz after losing only one bud to a spot of rot. Maybe would have been an extra eigth, so no biggie. 6.5 oz seems pretty lame, but the Kind never went above 75% power & is a little undersized for my footprint, so I’m happy with it. Lots of jars, so you can tell it’s a little fluffy. Will be burping these for about a minute a day for the next week or two, & then for a little longer per day after the first week or two:
Thermpro of the past week: (This is the sensor kept even with tallest tops of canopy.) Leaf temperature offset widened to around -10f after switching fixtures.
Week 8 since the flip will be starting in a couple days. The box has been on cruise, & the only issue has been the difference in plant height. Been pruning & partially pruning various fan leaves to try & get some light down to the short stuff & to keep the congestion down, but I’m not expecting much from the right-hand plant:
I’ve been starting to dial back the nutes a bit, & it should be due for a res change soon, & I’ll be staying with the factory week7 bloom nute ratio for the next three weeks. Also I recently started to add a bit of silicon & a pinch of epsom salts:
Thermpro near top of canopy, from the past week. Leaf temp offsets running around -8, depending on where I measure.
It seems to run a little tighter on the taller stuff, & a little wider on the lower stuff: The plants have been moving around 1/2 a gallon of water a day total lately, maybe a little more or less depending on ambient conditions.
Light will be moved up soon. Currently seeing around 1000umols at the tallest, most well-lit leaves. The short stuff is only getting around 500 or less, but it is what it is. I could do something like shade the taller stuff & turn up the light, but right now everything is moving along without too many issues yet.
It’s due for a res change today. I’ll get to it tomorrow, & it will get the same nute ratio & ppm as last time. I’ve been running around 700 to 725 ppm for the past week, after cutting from around 750-775 to 650 & seeing that it was too weak. Light was raised a couple times over the past few days, & everything but one of the taller buds should not be getting too much light. Light is at 75% power. Some of the taller stuff has some minor foxtail buds. I may stagger the harvest to try & give the lower stuff some more light & time, depending on how everything goes.
Moving the light up caused some changes resulting in a few temp spikes at the top of the canopy, until I finally got around today to lowering my temp fan setpoint. Thermpro at height of tallest bud, past week:
Tomorrow will be the beginning of Week11 since the flip. I added some more guy-wires, & did some more minor defoliating. Nute ratio is the same as before, but I tapered the nutes slightly to get the upper leaves to start fading a little more.
Upper-canopy Thermpro of the past week: Temps settled down after tweaking my temp exhaust fan setting.
The big dips in lights-out temp & rises in RH on Wednesday & I think Thursday are from the main breaker being shut off while some work was being done. I was doing a bunch of electrical work last week, I don’t remember exactly what days they were.
Probably a little drier than it should be up top, & I could run the RH up a little, but don’t want to cause issues with the lower stuff. Right now the balance of compromise is not too bad between the taller & shorter plant. The tall upper leaves are still tacoed, but they are still transpiring & mostly plump with moisture, & staying around 6f below surrounding air temps, & the buds are staying around a degree below. Nutes have been tapered off a little, so some of these upper leaves will probably start to yellow more anyway, & I’m thinking the top half of the plant will be ready to harvest within the next few days. Then maybe I can give the lower stuff some better conditions until they are ripe.
PPMs have been around 675, & I just switched my add-back to the final nute ratio on my chart to bump up the P-K numbers a little more. Addback lately has been around a half-gallon a day. I also slightly bumped up my small Si dose from .25 ml to .5 ml / gallon to help bump up the overall K number a little more. Probably could have done that a week ago, & am probably showing them too much N, & a couple lower buds are pushing out a couple tiny new leaves, but I wanted the lower stuff to stay green for the staggered harvest. I skipped doing a full res-change a few days ago, but have been doing partial res-changes mostly every day since then, pulling out an additional 3/4 gallon or so before adding back. I’ll do a full change with the final ratio after the first harvest. pH has been pretty well-behaved, only requiring minor daily adjustments & not crashing, & It’s been running around 5.8 to 6.2.
Chopped the left tops, & did some minor defoliating & strung up two new guy-wires for a couple wayward stalks. Probably going to keep most of the stalks positioned where they are now for the most part, although I may try to move the tallest stalk on the right plant a little more towards the center, & then move the couple of stalks against the right wall away from the wall a little.
I found one small sugar-leaf browned out & wadded up against a lower bud that I chopped off. I plucked the leaf loose & the bud it was stuck to looked like I might need to watch it. But overall everything looked nice & fresh except for that one leaf & maybe the bud it was stuck to. I meant to mark it with string but forgot to, it’s in the Sweat-Tent somewhere.
Thermpro in the Sweat-Tent:
Inkbird RH controller is running the exhaust fan set to 67% target with a 2% offset, so it exhausts at 69% roughly. I’ll start dialing that down bit by bit. Ambient RH is pretty dry right now, so RH gets pulled down a lot in the tent whenever the exhaust fan hits. Oscillating fan on a cycle timer runs low-speed for one minute, & then off for three minutes. That is probably causing the small steps on the trace.
I’ll spend some time checking & re-dialing stuff in the Main Cab tomorrow as needed, & it will get a full res-change. I left everything as it was before the chop, although I took another two minutes off of lights-on.
I tore them off, but they’ve probably been there for a while. Also I’m guessing that more will show up. None of that bodes well for letting these things simmer for a couple weeks to finish up, if stuff has been/is getting pollinated. I don’t see much evidence of finished seeds on the existing buds except for a couple around the nanner sacks, but I’m figuring that the fresher buds on the right plant might be getting dusted now. I tore one calyx open on the top of the tall bud on the right plant thinking it might be a developed seed, but it was not. I’ll let these go for a few more days to see what happens, but I might be cutting everything down sooner than I want to, because the trichs are still finishing.
Pic from today after tying up/ moving a couple buds around, & some minor defoliation. Also did a full res change.
I also lowered the fixture to bump up the ppfd by around 100 to 150 more than before, & am now getting around 700 ppfd around the tallest bud, & around 650 across most of the canopy, & 550 to 600 around the edges. (A little more, since my meter doesn’t pick up the far red diodes in the fixture. But they add only around 15% more.) That would probably be enough to help these finish without shocking them with too much light.
I also bumped up the RH target by a couple points. The high temp exhaust fan is hitting a little more often due to the fixture getting lowered & heating up the airspace a little more quickly, so the RH is getting pulled down more often, & I was thinking I wanted to bump up the RH a little bit across the canopy compared to the ‘old’ canopy anyway. So now I’m getting a little higher RH at the canopy than before the harvest, but it’s getting pulled out & down more often. Should be interesting to see how the plants react to all of the little changes, if at all.
Trimmed the fan & sugar leaves off of the first part of the harvest. It’s a little dry in there, been swinging between 45 & 55% rh, although the leaves & buds have not dried out yet. Temps have been low in the 60s mostly, so that is probably helping slow that down.
It’s been around 5 days since the first part of the harvest, & these still growing probably will need another five days or so before they are ready. I did a partial res-change today, pulling out an extra gallon. The plants are drinking around 1/4 to 1/2 gallon a day. I’ve been keeping the PPMs at around 700 to 720. pH has been running around 6.3 & had been moving up a little since yesterday, so I moved it back down to around 6.0 during todays addback. I’ve been doing minor defoliation as needed, & moved a couple stalks around to create some space between them.
I have not seen any new nanners pushing out of the buds on the left plant, or any at all on the right plant. I saw a couple calyx on the top of the tallest bud on the right plant that looked like they were growing seeds, so I pulled them off to see, & there were no seeds in them. Maybe they were still fresh & developing, I don’t know. I’ll be surprised if I don’t find some somewhere, but hopefully not a lot if so.
The canopy is pretty even, so I’m seeing around 71f leaf temps across most of the top. A bit chilly, but not going to mess with it. Bud temps are running about 2f higher than that across the top, far below my limit for bud temps, & the air temp across the top is running around 7 or 8f above the leaf temps.
Thermpro of last week: This is from the middle module hanging along the right-front corner, even with the canopy top. I know from testing that the front right corner is close to the conditions near the center at the same level, so that’s why I keep them there.
Been around 10 days since the first chop, PPMs are down to around 630, pH has been running around 5.9 thru 6.2. Been doing minor defoliation daily. Trichs are mostly ready on the left plant, to nearly ready on the right plant, although it will probably be able to use a little more time when I chop everything. I’d rather get everything out of there sooner than later at this point.
Middle Thermpro for the last week: Ambient conditions have been temporarily more humid for the past couple days so far, so my cab RH has been creeping up during lights-on, even though I lowered my RH target down a percent a few days ago. Leaf temps have been around 71f across the canopy.
…but that’s probably about all I’ll be able to get away with since I’m leaving the roots in, & also the right plant is feeling the nute reduction (down to around 530 PPMs today), so it’s going to need to go soon anyway.
…then went back in today to cut up some of the fatter new buds. I ended up with four sticks total, the first one has four hands & that was the first chop. The second has four hands & was the second chop. The third has four hands, & the fourth has three, those all being from the second plant/ third chop. I’ll go back in tomorrow & remove the fan leaves & some of the sugar leaves. RH is running between 60 & 65% right now. It got a little higher after the second chop went in, running around 62 to 68%, but I dialed it down a little before the third chop to where it is now.
Probably will be sending most of this to the bubble-bags. Not sure if these will be worth jar-curing, but the hash should be pretty good. Too many question marks for me to jar cure these I think. Will I be curing seeds? I haven’t found any yet, but haven’t really looked either. Will I be curing nanner pods with pollen that will turn south later on? On the left plant I have found some nanner pods, & there are a some questionable spots which are nanner pods below the surface or calyx which might be rotting, or at least not in the best of condition. Plant on the right I haven’t found nanners,
but possibly seeds are there from the other plants nanners. Plant on the right probably could have used a few more days trich-wise, & while the buds came out beefier than I expected, they are also on the leafy side & are underdeveloped due to being shaded for much of flowering. Probably better to just bubble hash instead of jar-curing this stuff. Also I am low on bubble, & still have some jars of flower.
Will be taking a little time to re-set the Main Cab for the next run, which will just be more of this strain. Might start with two & pull one, if it looks like they aren’t growing similarly.
Edit : I accidentally reposted an older pic of the roots in the bucket. Here’s the more recent one that I had intended to post, right before the final chop:
nice work over there. Awesome cultivar
