10 percent h2o2? can u be more specific
That wont work. It will only take the problem away temporarily. PM spores are really hard to kill completely and every grow you have from here on out in that room will get PM unless you eradicate immediately. Sulfer burner is the only thing that worked for me. I had a serious problem and thats all that worked to get rid of it. You got a ways to go on those plants and usually when you see PM spores on leaves its too late for sprays etc, its already infected the entire plant, plus that only slows it down for a little while then it comes back with a vengeance. Check out some videos on a cheap DIY sulfur burner and order some horticultural sulfur from ebay for cheap. Dont buy into the already made sulfur burners for 100+ they are bullshit and you can make one from a dollar store scented oil burner and a tea light candle. Till you get all that stuff, spray the plant with 1/3 cup 3% peroxide in a quart of water with 1/4 cup raw apple cider vinegar, lift the pots off the floor a little so air can get underneath.. Let the temps in the room get to 95-100 with air circulating fans on, for 2 hours that will kill a lot of the spores and control the problem temporarily. Then keep your temps ranging from 82-85 and that will slow down the growth and spread till you get the sulfur burner. Good luck PM is a bitch, oh and sulfur will kill any bugs in there too as a bonus

On a plus note I noticed the plants that got infected with PM developed much more resin and trichomes to protect themselves inturn being much more stinky. Even if you have a plant that is white with PM its not the end of the world. Cut the stalks trim them the best you can and then give them a delicate dunk and rinse in 10 percent peroxide bath, so as notg to break the trichomes, rinse with plain water then fan dry.
