Well, after searching and reading here I found that spraying baking soda on my plants leaves would knock out a bit of powdery mildew I had going on a few leaves/plants. So I mixed it up @ about 1tbs/qt and gave the plants a good spray down, I'm 40 days into flowering and was only seeing a few small white spots on some of the fan leaves so I shielded the buds as best I could. Well the plants took it well and hopefully, removing a couple plants, moving a fan, and nature lowering the RH will prevent any more pm. BUT, it seems that the spray left a white residue on the leaves. It wipes right off and they don't appear to be damaged at all. I was thinking that as long as it wasn't harming the leaves that I would leave it to help with the PM. What do you all think? Leave it or remove it?
