If u really love your plants and dont want to get rid of them here's what i bought on advice from keyplay dude know's his stuff and i havent seem pm since i bought this stuff
I Feel your pain, brother. You are really too late in the game to alleviate your PM problem completely without screwing up your flowers. PM is systemic, so its in the plant. It might have been there before you flipped.
Banner Maxx is a excellent source for prevention and irradication:

Do a run off in your 2nd or 3rd week in flower using 1/2 tsp per gallon. This will kill the bad pathogens in your plant and you will not have any problems throughout the rest of your cycle. Use protective gear!.
Try Quantum Growth for excellent results:

I mix 15 ml of Quantum Growth with the Banner Maxx and a drop of dishwashing detergent. Killer results! Microorganisms to the rescue as a back up.
