WW Klawing, yellowing upper fan leaves, and tip burn

[Rich96]

Notice the difference in upper leaf color in comparison to the others on the one plant. I noticed this 3-5 days ago and it does not seem it has gotten any worse really but this same plant did have by far the most completely yellow lower leaves and leaves all over the plant in general mostly have atleast some yellowing.

The mutant has always had darker and slightly different shaped fan leaves but about a week ago I noticed klawing towards the top on all of the fan leaves.

Noticed burnt tips on a separate plant (just a few) a few days ago as well.

Ticket info:

White Widow Autoflower from ILGM

• Method: FFOF soil w/ solo cup dug out of center and FFHF filled in

• Vessels: 5 gallon fabric pots

• PH of Water, Solution, runoff (if Applicable)

Water is tap from a garage spigot filtered with a cheap Camco inline RV filter (watering twice weekly; once with Cal Mag 2mL/gallon strength other time with nutes which so far have started with half strength RB plant booster and flower time fertilizer) about a half gallon per watering and I wait until they completely dry out again. Water is always pH’d to 6.2-6.7

**update (I copy and pasted this from a ticket I posted a little over a week ago when I was worried about lower leaves dying of which is normal from what I was told) runoff PPM of this plant specifically was at 850 yesterday when I ran my once weekly plain watering which is down roughly 200 from last time when I fed nutes.

****update 2 here is recorded feeds

• PPM/TDS or EC of nutrient solution if applicable

Plain filtered tap 200-250 ppm
Tap w/ cal mag 300-350 ppm (between about 2 and 2.5mL per gallon)
Tap w/ nutes 700-800 ppm

***update I have since stopped using the Cal Mag with my non mute waterings in the last week.

I’m definitely seeing some excess nitrogen. I’ll have to look a little deeper when I’m not at work.

Good post lots of info so I’ll help you get to the bottom of this.

First thing I noticed is the plants are not labeled or the plant pictures are not labeled.
So this makes things hard.

Your in soil and your feeding half strength if I read that correctly? 800 ppm is half strength?

What’s the feed chart say ppm wise for the week of flower your in, match that to your run off ppm.

If your ppm is to high flush, to low feed.

When feeding soil grows I find it ideal to wait until the run off ppm drops below 800 before feeding, otherwise the nutrient levels may be to high and juggling feeds with soil nutrients is always a pain.

There are two pants there that I see are clawing, the rest are hard to see true colors because of the grow lights so please ensure that lights are off flash is on for photos as it will reveal what the plant truly looks like under correct lighting.

By the numbers I would suspect 2 & 5 to be the ones clawing but this is a shot in the dark.

Ph on run off in soil is not accurate, a soil slurry sample is the only accurate way to obtain a PH.

Generally your doing really well and these are minor issues easily fixed.

If all else fails, put them in the bathtub, flush them all and the give them a full feed with 20% run off.

[Underthestairs]

you got far better here than I would have come up with.

[Rich96]

Didn’t even realize I didn’t match the plants to the numbers in my post and I will do that as soon as I am home from work…what a great response and I appreciate all of that. As soon as I can I will get back but I can tell you I know off top that number 6 is the one that’s been sort of a mutant from the start and has the worst of the klawing

@Rich96

PPM of this plant specifically was at 850

Soil runoff should be no lower than about 2,000 ppm. That is great data which tells you to supplement. I have no experience with what you are using so not sure how to advise. Monitoring runoff TDS like this can tell you when to supplement and when to just water. At some point in flower, unless in a monster pot or the ground, you will have to treat your soil as coco or peat and provide all the plant needs yourself.

[Rich96]

Okay…say the solution I mix for feed with the flowertime fertilizer is 1600 ppm. If I feed that to a plant that’s under 1000 ppm at this point would my runoff be even more than that 1600 after running thru the soil? The ppm of my filtered water before adding the Flowertime fertilizer is around 150 I believe. Just curious on what you would suggest with this specific situation.

How old are the plants? When did you first see pistils?

[Rich96]

I just put more sticky notes clipped around the pots so you can see which I which from all angles…should have already done that lol but here they are numbered

1:

2:

3:

4:

5:

6:

Note that I took these pictures towards the end of its normal 6 hour lights off period so that’s why they look sleepy.

I have not watered since and I can tell I will for sure need to water tomorrow(right on schedule) and it is the water w/ nutes day.

Numbers 1 and 2 seem the most normal of the 6

Number 3 is the one that seems to be moving the fastest, has a foxtail with a fat cola (how should I prop this bad boy up?)

Number 4 is the one referenced above with the darkening tips seem to be slowly getting worse but I haven’t touched these in days…

Number 5 just last few days noticing the burnt tips

Number 6 has been a mutant since birth and started klawing weeks ago now…

Runoff PPMs from the journal above (last plain watering)

1: 720
2: 1270
3: 730
4: 800
5: 1120
6: 770

I also want to mention I noticed crazy high runoff ppms a couple times ago when collecting the data and noticing it super high on the first initial little bit (like 3-4 fl oz) so I would rinse the little pot rolling stands that have the indentations in them that make collecting runoff easier for me and I make sure I get a decent amount of runoff (about a half solo cups worth typically) to help ensure accuracy. But can the way I water affect my runoff? I typically dump 1L in the pot at a time with a measuring cup about 3 seconds per liter and then let it drain into soil trying to keep it even and do it again. Last few times I have to give them 2.5-3L to get adequate runoff so i think I have gotten it down.

Please help lol

I was planning on removing some of the larger fan leaves and lower dying leaves when I water tomorrow but not too many…I’m afraid to stress her out too much

[Rich96]

Back into the tent they go

[Rich96]

Sprouted 8-2-2021

I would say first signs of baby pistils would be about 9-1-2021

First sight of pistils usually considered first days of flowering or when you start to see hairs?

[Nicky]

Nice work on the stickies and the spacing, much easier to read.

Water only for #2 & #5, see what their run off is before you feed them with nutrient water.

Your just starting week 4 of flower let’s say.
So 950 ppm is your target 6.5 ph
Make sure they get a good healthy amount of run off, it’s very important.

For the fox tails, it’s because light is to close or to powerful or heat is to high shoot for 80f/27c

Have learned about dialing your lights in?
Here is how to do it, if you want skip down to the app part.
Please give my thread a like and read it, great video to.

Start using DLI

Daily Light Interval (DLI) is a quick and efficient way to calculate how much light our plants are receiving within a 24hr period, allowing for easy light adjustments. DLI will help you and the community to better understand your lighting in a more universal term, leading to clearer communication of what the true light value is. Almost all smartphones have the ability to use an app (we will get to this don’t jump the gun) in order to calculate DLI, and if that is not an option a cheap LUX meter…

Your doing well keep it up

[Rich96]

Will do thanks I’ll update tomorrow! And I do have the app with the ppfd meter that I think is awesome.

I am a new member and cannot make a post.
Autoflowers by fast buds only 5 are having an issue 3 different strains.
3 and 5 gal pots.
Temps reach 84 during the day at 65% humidity. Around a 1.5 VPD I think.
I feed anywhere from .8-1.5 EC at 6.2-6.3 PH
Blue labs pH and EC meter.
Led & hps
Haven’t metered run off.
Fox Farm grow, big bloom. Remo Cal mag. Bio Biz Top max. GH Ph up & down.
Maybe I don’t let the water buffer enough before metering if it’s my PH.
Don’t roast me I’m not a pro. I feel like I definitely should know what it is but here I am
Potassium burn???

Update:

Okay so yesterday I watered them. 2 and 5 without nutes like suggested. Just today I pulled them out and trimmed most of the dead/dying leaves off and some of the larger upper fan leaves and tied them down again for another round of some LST. I used about 75 percent strength on the flowertime on the rest in which I did feed. I also upped watering to about 3L each which gives me much more runoff than before which was suggested above, but nothing too crazy.

I also moved my tent to where my AC unit can blow directly into it until I get this bigger oscillating fan on Thursday to go on the canopy to get my temps down a few degrees from the 82-83 range when lights on and so far it seems I have gotten it closer to 80 this way but only had a few hours to test as lights go back on in a few hours.

Water before nutes added was 110ppm 9.3 pH. After adding 10 grams of flowertime to 12.5 L of that it was 570 ppm 6.9 pH (this is about 75 percent strength)

Target ppm for week 4 flower is 950

Remember this time I only plain watered numbers 2 and 5.
