The others have you covered on earlier post so I’ll spare repeating them.
Yes, may take a while before they get to falling off but they won’t repair themselves.
Just stay the course here and you should do pretty good. Don’t worry about overwatering, just try to feed around time lights come on. As long as your environment is in check they will dry out quickly.
No kidding, we love Stillwater! We go every year 2-3 times in the summer, Lumber Jack Days is pretty cool. Stayed at Hotel Crosby a few times, distillery across the street is pretty tasty…I could go for some Nacho Mama’s right now.
The reviews look pretty good for those AC Infinity bottom feed trays, I have a 4 pack enroute, they will arrive before I leave. So now I can fully soak prior to leaving and then fill the trays up. I do not have the AC fabric bags, I assume all fabric bags are pretty similar, hopefully they will be fine.
The question is, do I just fill the reservoir with straight PH’d water or add nutes also?
Mix and add your nutrients at 900 PPMS and PH at 5-6-5.7. Normally I would recommend 5.8 but it’ll rise a little sitting for a few days 
Update
Day: 37
2nd Full Soak Day with 20% runoff
Increased Lights yesterday to 50% at 30", they appear to be taking the uptick well so far
I didn’t notice anymore damaged leaves…from the calcium and magnesium deficiency
Feeding
PH: 5.83
PPM: 820
1st Official Runoff Numbers
Amnesia Haze
PH: 6.79
PPM: 625
Northern Lights
PH: 6.90
PPM: 770
Blueberry
PH: 6.80
PPM: 840
These numbers are all high
Correction/s: Flush? (I’ve read about them, I assume run water through, with a lower PH and no nutes?)
Questions/Worries
In what range should my runoff be?
How long do you wait after a flush to introduce “correct,” PH’d water with Nutes?
Yes that is a flush. In soil its 3x the volume of the pot in ph stable water (water with at least 300-350ppm tds) phd to 6.8. Not sure about coco although I inagine its the same only with an coco appropriate ph.
Flush and feed in the same session. I flush, checking ph run off at every few gallons till its in line, then allow runoff to stop dripping, takes about 10 or 15 mins then mix up a feed and slowly pour in the feed. Slower the better after a flush.
Now that you know how to flush, I dont think you should just yet. Track the trend of your runoff for a couple of water/feedings see if it is maintaining high or if its going down as I suspect it will.
A tip for tracking. I use an app called Grow with Jane. Its awesome for keeping track of everything and its free up to like 8 plants and 2 tents. Fully recommend it.
If your plants look fine do not flush them. I never monitor the runoff ph in my coco plants. Only need to worry about ppm. The ppm of your runoff should be the same as input or up to +300. If its more than +300ppm you need to either feed til more runoff or more frequently. If then it doesnt change it then lower your ppm of your input feed a bit.
Always silica first followed by cal mag. Then base nutes.
Yes on the the PH being high for coco. Personally seeing as their all a solid point too high you have 2 options. Flush with PHd water at 5.6 or feed at 900 PPMs at 5.6 to liberal run off. The run PPMS you currently have are in range for their growth stage… a tad low but not too bad. I shoot for 900 in veg and 1000-1100 through flower. I would try a feed at 900/5.6 to a good amount of run off and test the numbers. If you choose to flush, use 3 times your pot size and go slowly and check the numbers about half through the flush
Noted Cooter, thank you!
That makes me feel better, that I am not as far off as I thought I was.
I created a spreadsheet, so I enter everything in there along with pictures of the good and bad.
I saw the Grow with Jane App while looking for another App. The App would be nice being I have to bust out my computer everyday to enter data. Thanks for confirming the App is worth the time to use.
Day:38
Using recommendations from my first full runoff numbers, I will;
Updated Pictures:
Amnesia Haze (Pay attention to the tips of my younger leaves)
Blueberry (Pay attention to the tips of my younger growth)
Northern Lights
In this thread alone there are at least 4 ways suggested to make a mixture for feeding. Below I took everyone’s main preference and came up with this order:
OG, the Pro Version of the App shows it measures DLI, do you use this measurement OR do you go with LUX to PPFD to DLI via conversion calculator?
I use DLI, and like to check the PPFD/Par to just to see where it is. The app I have does both
Free version (Android) does DLI, I use it couple times a week.
Hydroguard is last, I understand that ph up or down will kill the bennies so it has to be in solution before adding them.
In this post from my journal I give the web adress for an article about mixing. Couldnt link ot directly because of forum rules but you can find it using info provided. Its a good read.
Perfect thank you!!
You are most welcome my friend.
Update: Day 40
I hope everyone is doing well?
I hope everyone has a fantastic Holiday Weekend with friends and family!
As you know from above, I was lacking in nutes and I was making my mix at 6.8 PH, which is really high for Coco.
Was recommended that I make the next few mixes at a PH of 5.6 - 5.7
I did not bother checking runoff until my 3rd feeding with the adjusted PH of 5.6 - 5.7
Feeding:
Day: 38
PH: 5.61
PPM: 933
Nutes, Calmag
Day 39:
PH: 5.68
PPM: 930
Nutes, Calmag
Day 40:
PH: 5.75
PPM: 926
Nutes, Calmag, Silica, Hydroguard
20% Runoff Day 40:
Amnesia Haze
PH: 6.65
PPM: 1300
Northern Lights
PH: 6.81
PPM: 1300
Blueberry
PH: 6.68
PPM: 1200
Questions/Concerns:
With 3 days of feeding with a lower PH, my PH has not really gone down at all, thoughts?
What I noticed; I mixed Silica first and waited 20 minutes. I then check PPM to see how much nutes I need to increase my PPM. I then add the Calmag. I noticed after I add my nutes and get my PPM to 900, when I add the Calmag it increases my PPM by 175 to 225 which in turn makes my PPM around 1050+. SO to compensate, I add nutes to get my PPM to 650ish then add the Calmag, then I usually fall closer to 900.
Wouldn’t it be easier to add my Silica, then Calmag, then Nutes, it will be easier to reach my 900PPM goal
Should I stop worrying about runoff PH as you suggest above @CooterJuice and just focus on PPM?
With the runoff being high in regard to PH, the below pictures are from Day 40, this is the best they have looked to date, see pictures: (Pictures were taken 10 minutes after lights on, still a little sleepy/droopy)
Amnesia Haze
Northern Lights
Blueberry
Id say your good as long as your tds going in isnt above 1200 If you add all your stuff and tds is too high for comfort add more water until tds is where you want it then ph solution. Or if runoff tds comes out way out of target, run straight ph’d water through the medium until runoff looks better.
Im not sure I understand what you mean. It would is easy to add all the stuff you need, then add addtl water till you get where you want. Often my feeds are in the 12-1300ppm range it really depends on the size of the plant as to how it is affected by the tds of the feed. Early in veg a feed that high would burn the plant but later in flower not so much.
Yes. Runoff isnt an exact representation of rootzone ph its more of a guide. If its way off then you have to worry and make adjustment if its close, and your plant looks good then you are good. Tracking the trend is the main function of tracking it. Alot of things can affect the runoff ph also, pouring too fast would be a big one.
