I just went through the same thing with my outdoor plants. I put about 20% milk in liter spray bottle. Sprayed all the plant and buds without issue. It actually makes the leaves nice and green and shiney. The powdery mildew came back a couple days later. I bought a pound of Potassium Bicarbonate on Amazon for $8 and mixed 1 1/2 teaspoons in the milk/water solution and sprayed that all over the plant an buds. It seems to have gotten rid of it. The humidity dropped big time right after I sprayed the plant so I'm sure that's helping also. I like the fact its all natural stuff on the buds. Hydrogen Peroxide works to but I haven't tried it
I've read many times not to use neem oil on the buds as it will leave a nasty taste. Don't know but I dont want to risk it
here is the stuff I bought

Thanks... will look into the Potassium Bicarbonate... i was worried about spraying the buds so late into flower but this looks like a good solution.
