What remedy??? I'm relying on Serenade once a week, tho I'm far from harvest and haven't seen any harm from it. I grow in a high humidity area and have lost a lot to botrytis (grey mold) on my last grow and am trying to plan ahead. Never heard of burn from Serenade, pls advise.
With one week to harvest, I would have just removed the affected leaves! Rinse them off well with distilled water when the lights go off and add a fan to dry them faster. Add a week to your finishing time. Praying a bit wouldn't hurt. Next time try this - Stop Powdery Mildew Naturally, with Milk - Planet Green Safer, rinses off easily, and any that falls on your soil is changed into ferts! Granny
I used a baking soda water mixture that I have used before. Just not this late into flowering. Its supposed to dry at a different ph and basically burn the mildew off without harming the plants. But I think the spray beaded up and just sat on the buds and leaves and the light burned them. I run my lights at night so when I checked on them the following day all the pistils had burned back and some leaves had too. I have already harvested and dried. In the curing process now. It could have been a lot worse. Buds look decent now that they are all trimmed up. I'll post some pre trauma pics. Didn't take any after the burn.
