Hello fellow growers I’m currently growing 12 taho clones in my closet grow, very tight proximity to one another. I just defoliated and noticed white powdery mildew. most fan leaves are okay but about 40% have it, and it looks like small white circles on the leaves. It’s not to bad ... yet. I bought a spray that eliminates mildew and took all plants out. I wiped down all of the fam leaves with a brush in the solution, and wiped down the entire closet with disinfectant and cleaned my fans throughly. I’m noticing it’s coming back now again and I need some tips to save this grow! My average humidity is 40-50%, my soil is coco with 444, worm castings; just top dressed with nitro bat, worm castings and 484 putting them into flower, I use ro PH around 6.5, on 12-12 light cycle, I have an cloudline t4 inline fan with a charcoal filter, and one box fan moving air around the room.
