They're right on track!! ^_^ looking great for day 14!
Love that space ... woah .. look at them big assed round autopots!! Gonna be a jungle soon!!
Thanks @blue! I'm definitely hoping for a jungle!
Fingers crossed

Good luck to you.
Hopefully we are all working towards fixing the problem with unnecessary regulations.
Get out there and vote for your freedoms!
Luckily I'm in recreational land at least; we just need our state legislature to get their shit together and pass the 4 or 6 plant law already. Soon enough. Really wish I could journal it up though. Running Zamal Express, Double G and CDLC in autopots with megacrop, etc. so hopes are high!
Day 18 | 78 F | 45-60% RH | Lights = dimmed (150W each) @ 36" = 18,000 Lux/262 PPFD
Running into some problems now. Not entirely sure what everything is.
The girls were closing their top growth all the way about midday on their light schedule and the outer leaves were drooping a bit. I assumed light stress and raised the lights a couple inches and dimmed 15W each. This has had a small effect.
Looks like I have a Magnesium deficiency so I will be giving them an Epsom Salt foliar feed rights at lights out (running 20/4) to help correct the issue quickly.
May have a Nitrogen deficiency on one as well.
Lockouts due to PH, PPM, salt buildup are most likely the culprit. I am going to bring them to the tub today and run a gallon each through pots with nothing but Calmag and Megacrop, leaving the sweet candy out.
Current feedings are at PPM at 490
What PPM should I bring my RO to with calmag?
What total PPM should I be feeding at almost 3 weeks old?
I suspect that I have more watering issues (cant figure out this coco thing). I see one report to make sure top never dries out, another that says to water everyday, some say to wait 5 days between watering at this stage.
Drainage is most likely an issue as well due to top watering and the girls sitting in their Autopot homes. Maybe the bottom isnt drying out the right way?
How much longer before I can fill the reservoir?
Any feedback would be helpful.

Hello - I've had a few thoughts.
1. Have they had any calcium?
2. Are they sat on cold floor?
3. Some of them are pretty much ready for the autopot=on (by my method of leaves to the edge of the pot)
I'd knock up some epson salts spray and give em a dose.
here's some science reading that someone cleverer than me wrote and someone cleverer than me (@Waira) got me to read ^_^
BIOCHEMICAL SEQUENCING OF NUTRIENTS
It is important to understand that plants have a defined biological sequence of nutrient uptake. This starts with Boron, which stimulates the root system to leach sugars into the medium.
These sugars feed the microbes, which transform silicates (Si) into silicic acid through a process called silicification. Silicic acid enhances Calcium uptake, followed by Organic Nitrogen (from L-Amino Acids), Magnesium, Phosphorus and Potassium.
These elements should be present in a bioavailable form to plants. If one nutrient in this sequence is not available (or less available), the uptake of all other elements in the sequence is more difficult or missed. It is very important to respect this sequence in order to avoid mineral deficiencies and/or nutrient uptake problems.
A common nutrient problem in indoor gardening is Calcium deficiency. This is because Calcium is immobile, meaning it doesn’t naturally move into and throughout plant tissue. Also, Calcium is pushed away by other minerals that are often added in large quantities, such as Nitrogen (as Nitrates) and Potassium.
Looking at the chart above we can see that Calcium is near the beginning of the sequence. And if Calcium uptake is limited in any way then all other nutrients uptake and availability will be affected. There are many other problems with Calcium deficiency
that will be discussed later. One of the best ways to increase Calcium availability and uptake (other than chelating with amino acids) is to optimize Silicon levels in the form of Silicic Acid. This is the beginning part of the biochemical sequence. In most indoor applications, silicic acid is rarely available because of the time it takes soil micro-life to naturally convert silicon.
Thank you for the comprehensive response.
1. they have had minimal calcium added, 0.5ml Calimagic per gallon
2. They are on the floor in my spare bedroom. It is carpeted, padded, and insulated. Floor temp with my IR thermometer is 68°
3. I will run the lines in the next day or so and hook up the ones that seem ready. I will give the rest a little time to catch up.
They will get an Epsom spray today at noon. Then I am going to give them a good watering after lights on at 4pm with plenty of runoff to help flush any potential hidden issues.
No Worries mate!
Sounds a little low - I use half a cap per 5 litres (which must be a few ml) - think i've got the same calimagic.
That sounds ideal! (I was asking incase it was a cold stone floor)
Sounds Good!

Hi i had not seen your thread. Not an expert but i'd like to add a few things...
Not sure if i missed it but what pH are you using? I've had your same issue and pH has been the main culprit so before upping anything make sure the pH of your fertigation is within the correct range (5.8-6.2) with 6.0-6.2 being better for Mg.
And if Mg is actually def, i'd just add a bit of the epsom to the feeds instead of a CalMag product (usually adding Ca and N that might not be necesary in your case) but not sure if this is actually better. @St. Tom any idea?

PH going in is between 5.8 and 6.0. My guess is that my PH is swinging inside my coco because of the RO water.
Or the PPM is high inside due to the lack of runoff at this point?
