any advice or experience from bay area growers is appreciated, this stuff has been on all 3 of my crops and althoughi 've gotten ok at containing the disaster, i'd like to elimiate it.

for the record, i'm very good about humidity very rarely over 45%, i've tried every normal remedy under the sun (serenade, milk, lemon juice, baking soda, safergrow milder cure. uhm... yeah...) the best i think i saw was milk or serenade, but it doesn't cure it, just knocks it back for a while.

there's an interesting article in hemp diseases and pest, management and biological control: an advanced treatise' that tells humidity isn't enough for these strains because one of the two infectors of cannabis (sphaerotheca macularis / leveillula taurica) can germinate at 0% RH

cheap bump because i'm really really tired of pm. i know anyone in the sunset area of san francisco on here has to deal with this shit, please help

I'm in that 415. Yea that fucking PM go sulfur burn if your pissed but it's too late for you. I was in the same position as you. I just had to roll with serenade till I could harvest. Containment is what's up. After my plants were off all the stress the PM didn't fuck em too bad. (We had electrical problems and all exhaust went offline RH to 90% what started my PM)

Good luck man.

Oh yea I also bought a spray called Eagle 20EW it's for PM and supposedly treats systemic aswell. Using the serenade and the Eagle 20 I was able to get it under control. I pretty much didn't have any PM on my healthy plants but I had some small shits on the outsides of the perimeter who couldn't ride. It's expensive if that matters. 120 n some shit when I bought it.

anyone else?
