Just got the same problem, and another grower helped me out. White Powdery Mildew, also known as White Powdery Mold or just “WPM” to cannabis growers. Solution spray with : Milk (1:9 ratio of milk to water) Baking soda (2 tablespoons per gallon of water) Neem Oil (4 teaspoons per gallon of water) Hydrogen Peroxide (1 teaspoon of 35% H202 per gallon of water) SM-90 (1:5 ratio of SM-90 to water

What are your best experiences for treating white powdery mildew? (4th week of flower)I carefully removed all the leaves with WM on it, but i want to spray the leaves to hinder further development of the mildew. What are your best experiences? I've read about milk solution, maybe citric acid solution with a ph of 9? Can i spray the buds too? Thanks for your help!

Minor damage to a few leaves found today - what is it?I am trying to determine the cause of damage to a few leaves that was observed this week. It may be two different problems. On a few leaves, I see brown spots which may have originally been white. On another 2 leaves, I see a burn hole through the leaves with brown edges.

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?

how many times should we spray with milky water in case of powdery mildew when we are in bloom? do you have to spray with this solution every day?Several people here advised me to dilute the milk spray with water, I did it, I diluted 400 ml of milk with 1200 ml of water, then I sprayed the plants in the tent, since they are grown in scrog, it is difficult to get everywhere.
