UNEXPLAINED MILDEW

it's just in the air. it can overwinter on twigs, leaves, other organic material. here's one of the better summaries i found that isn't based on some monkey in their basement, like me. https://extension.psu.edu/powdery-mildew The organic home remedies suck a dick. i've tried them all. Anything that would be effective is probably not wise to use in bloom... so you have few options. continue to search through canopy and remove infected bits... use some sort of baking soda or h2o2 foliar spray often. It'll look like it does something for a day or two, but you quickly realize all it does is hide it from your eyes.. it's still there. i'm hoping a long break will allow me to get rid of whatever remaining spores there are.. i've had an issue for a while now. even though i'm not growing harvest crops year round, there are mothers and other side projects occurring that can allow it to persist... but 3months off after a very throrough cleaning should help. crossing fingers it's not wintering in hvac, lol.... maybe sulfur bomb the room after harvest.... once it's there you aren't getting rid of it. when you see it, it's been there 4-7 days in that spot alone. it's already spread by that point whether you can see it or not.. the fight is on... keep it at bay as best you can. I throw out any infected bits, but you could attempt an h2o2 bud wash when done too.. this will do nothign to the mycelium network that is underneath top layer of leaf/stem/petioles/buds etc.. so, don't think it "sanitizes" wpm.. cause it does not. it will reduce it. that is about all it ever does. you need somethign like 2-3% soaking for 30mins or more for this material and a little dip is not going to do it... soaking it that long will virtually remove all flavor, in my experience, and not worth it. definitely becareful of using it for any extracts... super high alcohol % might kill it, but you'll still have leftover spores and bits in your extract even if not viable to grow anymore. theer's no "good" way to use infected material unless you want to rip people off and make them wheeze and cough for a few days.
