Once you have it. It's hard to get rid of it. You can control it. Lower humidity to 45%. Mix up a gallon of water with a tablespoon of baking soda,1/4 cup of hydrogen peroxide 3% few drips of dish soap. Spray fan leaves. In the end you can do a bud wash. 5 gallons of water 1/2 cup of hydrogen peroxide. Soak buds with gentle wash. Do a double rinse of water and hang buds.

Homoginized milk mixed in water and sprayed on infected areas and around will keep it under control without harming anything

Powdery Mildew near end of flowering For the last few days, powdery mildew is starting to form on the leaves and some of the buds. I've cut where mildew was, lowered humidity to around 45% and increased air circulation by focusing a fan on the plant but it is still forming. Anything else I should do?

Small white spots on leaves in germination phase.Does anybody know if those small white spots are ok? I have water 7 pH and I add some citric acid to lower it to 6 pH, when I sprinkle the soil I lightly sprinkle the leaves as well and I'm not sure if it's the effect of dry citric acid or something else. Thanks.
