xXTheWolfXx It’s hard telling without knowing exactly what you have going on for an environment and where on the plant this is happening but I believe that could be the start of powdery mildew.. make sure your environment is bone dry with plenty of air circulation. Pick off the most effected leaves, spray plants and walls/floor liberally with 50/50 mix of 3% hydrogen peroxide and water with fan off for 5 minutes, then get a bunch of fans and dehumidifier in there and crank the dehumidifier all the way down to 30-40% RH and dry that grow room out..treat twice a day like this, it shouldn’t take more then a few days to kill off the powdery mildew, as long as you have a handle on the humidity..

xXTheWolfXx After you kill off the mildew, just keep you RH (relative humidity) below 80%

xXTheWolfXx Either that or get a exhaust fan and suck out all that humid air..the more biomass you have the more the need for better dehumidification…

Matta2377 What are your ph and ec readings?

Kushltier Ec 1.0 drain was 1.6 but I think I figured out the problem.. Fungus gnats… ive literally tried everything that’s one last possible problem.. and I see small white animals jumping through my cocomix
