I work in OK, running a virgin medical grow. We are just flowering our first round of test clones, currently about 16 strains, 70 plants or so In a shipping container grow. We did lose a chunk to herms. Running 6 inch Pargros with lines to each from a 50 gal res, Athena nutes, 35x5 ft table. 7 Phlizon, 3000 watt , 600 actual watts, full power. 1250ppm C02. Temps vary, from upper 60s to mid to upper 90s sometimes. (our main ac is down) humidity stays pretty stable around 60%. This is my first hydro run ever, and Its just me here. The owner has another main business and travels near constantly. I am learning as i go, with 16 different strains to keep happy. PH runs 5.6- 6.2 but usually closer to the middle. EC is about 2. in Res.
Lights vary in height from canopy but generally about 2 ft. some closer some a bit farther. We had yellowing of the Middle Leaves at first, I was leaning sulphur def, but our Athena has it in there, and our well water still holds like .6-.7 EC after RO, possibly some sulphur in there as well. I kept researching and kept watching the plants and eventually come to light bleaching, which i feel sure is what caused the yellow and red leaves. I turned the smaller Blurple LEDS off on the Phlizons to give the plants a break, showed the owner and he said to put them back and and let it go. We are 5 weeks into flower.
How big of an issue is the light bleaching, i have never had to deal with it until now. Since he wants the lights on full, my best idea is to shuffle the badly bleached ones to the outside and put the still green plants inside, the green plants in the pics are on the outside of the table. The last pic you can see a lower cola that hangs out back out of the light, up beside its sister colas, the lower one is green still, uppers are all discolored.
