Why is this plant wilting? Aeroponics

Tent was recently sealed for three days (R/O only in res), humidity was quite high, clones transplanted two days prior; looks like over/under watering, but it's got a good set of roots, and I'm as a loss. During this time a bit of cobweb mold showed up, but it's died off a good amount in the hours since I unsealed everything and turned back on the fans; plus, it wasn't bad to begin with. Lighting was 150W CFL while sealed to keep temps down, normally 800w.

I refilled the reservoirs with:
5 gallons R/O
40ml FloraMicro
80ml FloraBloom
6.2ml CalMag
5ml Epsom Salts
20ml ThriveAlive Red
5ml Floralicious Plus
pH 5.75 (has risen to 5.9)

Every other plant seems to be doing quite well, however this plant was one which showed little to no signs of the mold, and has one of the best root structures... :/

My best guess at this point is shock from the high humidity to low humidity change when unsealing the tent, but I tried a gatorade bottle cut up as a dome and it made no difference (now trying without and checking frequently).

(I know, plant problems forum, but when aeroponics are involved, it rarely results in anything; while last time I was doing a grow in this forum, answers showed up. T_T)

sounds like your giving them a lot of food for such a young baby, i don't give my clones anything but water in my airbuckets untill there about 45 nodes high then just a low gh nute solution water temps? when they get high they will wilt also...

I gave them a lighter nutrient solution initially, but that's when the sulfur deficiencies started; it might sound like a lot, but that five gallons is going to 32 plants, and upping it made them happier (or at least made the rest happier). *sigh* Maybe that was what shocked them, in addition to the huge swing in humidity; anyway, the first one which wilted is looking a bit worse, the second is looking the same as it was, however both have developed new roots since this all started, and the rest of them look great.

I'm going to check on everything, pH, etc. a bit later, and I'll post any relevant pictures.

Gatorade domes have one standing back up, the other looks a little better... should have left them on over night, but I was impatient; so, yeah, looks like it was the huge shift in humidity. The mold looked like it was dying off, but I poured 2oz of tea over each to be sure.

So, they stood up fully, I removed the gatorade domes, and a few hours later I noticed a little bit of wilt again. I'm spraying them occasionally and keeping an eye one em; also, I filled the net cups the rest of the way with hydroton. The lower leaves have yellowed a bit more, but the tops look healthy, and there's even a bit of new growth.

Why are you using bloom food at this stage? Also the Cal/Mag solution should do what the Epsom salts do for magnesium levels, if that is why you are using it for.

The epsom was for a sulfur deficiency.

FloraMicro and FloraBloom have enough nitrogen for cannabis without FloraGrow, this is a modified Lucas Formula.

I thought Id add my 2 cents to the conversation. I agree with the others who said you are probably over feeding. You dont need the full recommendation on the bottle. Id start at 1/4 strength and go from there. Are you checking the ppm? How come so much more bloom? I thought you still needed to go heavy on the micro during veg. I didnt care for the lucas formula with my areo setup. I got much better results from the full nutrient lineup. You should keep an eye on nozzles if you are running epsom salts. Its more salts to build up and clog. Ive had good results using a Mg supplement along side calmag. The pH rising is nothing to worry about. It happens, but keep an eye incase it climbs to high.

Jimdamick - Calmag supplements are more cal then mag. I want to say around a 75/25 ratio. Epsom salts work great to add mag back to the plants. If you dont have an actual purple strain, the stalks shouldnt be purple. That is a sign of mag deficiency.

I know Im new here and hope I dont come across as an ass. I just wanted to share what Ive learned and help troubleshoot. Peace, Understanding, & Pot
