So here in Buffalo NY this month has been pretty rainy and cloudy. Yesterday I noticed my one plant getting frosty leaves. So last night I gave them a good spray of neem oil.
That’s a bummer , Definitely looks like white powder mildew. You can mix a spray bottle with Proxide and water spray Affected areas lightly. 50/50 mix
Good luck
Ya looks like it, like @kellydans said give it a spray and then do a bud wash after harvest
I’ve also read you can use a mixture of milk and water.
Hey @Dexterado , I also read the same. I used a mix of milk and water One time on a plant outside did not work well for me.
I could understand why. Milk doesn’t evaporate very efficiently. I think peroxide or 90% isopropyl alcohol and water would be more effective. Works on bugs too.
I vote yes sorry
Well neem oil seems ineffective… think I’ll try hydrogen peroxide and water next.
@kellydans , I also tried a 20% milk / water mix on my pumpkin/ squash with no affect. What percent of peroxide/ water do you use?
@Fishyswaw 50/50 mix I spray Affected areas lightly with a mist bottle. It’s been several years since I had a problem. It seems like when I moved inside I left all my problem outside.
