I have had my plant in veg for 2.5 months in a 5 gallon dwc. im using gh floroduo, calmag and hygrozyme. i started noticing problems about a week or so ago with some random brown spots like the one in pic 1. next the plant started to droop and now all new growth is coming in deformed/clawed and the fan leaves are ranging from dark green to palish with little brown spots. After looking online and not being able to find the problem i set up a bigger res from 5 gal bucket to a 10 gal tote with an extra airstone. I also realised that ive been giving the plant distilled water for the last 2 weeks (before that i was using tap and everything looked great) so when i set up the new res i went back to using tap water. i also havent given any calmag in awhile so i added that. my ppm has been just under 700 and my ph has been 5.8 - 6.1. Is there something im missing? BTW my roots look amazing bright white and firm - however i was thinking maybe they had out grown the 5 gal bucket? they were really piling up
Has the humidity gotten really bad in there as the plant got big? That can cause the drooping, and a little spazzing out. Your ph range is on the high side. Some nutrients don't respond well in hydro above 5.4 There is actually no 'perfect Ph number. You're better off letting your ph drift through the 5.3 to 6.0 range to give her best opportunities at each element. View attachment 142808
