Are these all the same clone? When checking runoff also look at ppms. 1000-2000 is a general good number some plants will definitely tolerate much more.
I don’t have a nutrient breakdown for the fox farm grow but I’d say you should look into your nutrients. I use 4-18-39, calcium nitrate, and epsom salt and gh micro which is about the cheapest and most customizable if you want to look into it. There is a few nutrient calculator excel sheets...
I’d lean toward magnesium deficiency judging by purple stems, taco leafs, older fan leaves. Also maybe nutrient burn or lockout shouldn’t be ruled out. What medium are you in? Have you checked runoff ph? I run a mixture of promix and perlite and noticed I get magnesium issues with high light...
Likely the alkalinity of your tap water. As far as PH vs lockout you could have correct PH but the ratio of nutrients could be off causing a deficiency as well. K, Calcium, Mag ratio should be as close to 3:2:1 as possible during VEG and 4:2:1 as flowering progresses. I would check your PH of...
I consistently have runoff in Promix over 2000ppm and dont have much beside the occasional burnt tip. I would lean more toward PH or imbalance/lockout.
I have a 1/10HP active aqua chiller I haven’t really ran yet beside confirming it worked. Currently wrapping up a run in promix getting back into cultivation after a few years off. Have some vegging plants in dwc and wish to kick off the rdwc I setup a while ago. They are working well as a tray...

I’ve had fair results with this running without any chlorine and temps 75-77 for periods of the day. I use about 1/2 ml per gallon. Also use it in promix with same salt fertilizer as dwc.
Hydrogen peroxide is a cheap way to clear it up. Forget the ratio but can be found fairly easily. Could use pool shock to keep it away or could go beneficial bacteria. Really your choice. Pool shock is probably cheaper and is easy to maintain. Good luck
I would suggest phosphorus excess, in my studies and research npk should be closer to 2:1:3 or 1:1:2. If A and B are the same amount adds it would be 39.5N:55P:47K. Making P the highest amount... which could/would cause numerous lockouts including zinc. Good luck, take care!
Perhaps magnesium deficiency considering the purpling stems. I have a stand-alone dwc bin with 6or7 strains and only one clone showed similar cupping of the leaves. Heat and light stress definitely wasn’t an issue in this setup. Researching I came across possibly a mag deficiency. Sprayed with...
How about you queers all go to Australia and blow each other and talk about how good your “vaccines” are working?!? Make sure you’re in by nine that’s when the covids come out. .14% death rate is really really scary, but not as scary as republicans...
