I think i have a powdery mildew issue, is there any remedy? Looks like small dull white spots that i can wipe away with my finger
Got a gallon from amazon. Its very effective in killing algae in my growThe professional breeders that I know who have had this issue clean everything with 35% hydrogen peroxide. It is hard to get and dangerous to work with. Personal protective equipment is required. 1 drop on your hands will burn your skin and turn it stark white. But it is effective.
