My babies just caught a small case of PM, im on my first grow in first 2 weeks of flower...they are infected on the lower growth and in the corners of my grow tent. We just got our carpets shampood but the people did a crap job and it took 4 days for the carpets to completely dry. also i fucked up by over watering my plants. there was a pool of water for 2 days at the bottom of the trays. i have timmed alot of the undergrowth and infected leaves for more air flow. Its been about 3 days without water and the humidy has drop to 49%.. will the PM go away if humidy stays low? ive been using milk/water solution but it doesnt seem to help. what spray will knock the pm out for good? thanks guys any advice would be appreciated i hope this doesnt affect my yield/quality!
 
im battling this myself right now and seem to be winning, ive maintained ~40% humidity, removed some lower leaves to improve air circulation, added a fan to improve air circulation in the dead zone, then spray with a mixture of 250ml 3% hydrogen peroxide /1L of water, add 1/2 teaspoon of baking soda to the mixture, then PH adjust it to ~10.... spray effected areas with this approx every 2 days
 
dudes, i had serious pm issues due to neglect. bought some safer spray, sprayed all my girls down on several occasions and adios pm! when i had read all the threads here i started freaking out for no reason, the shit aint hard to kill. fuck a sulfur burner, if your having issues killing this crap, then you have an environment issue that you need to address first, peace out.

He's right it works!!! I took a spraybottle of milk and sprayed it all over a female which had leaves covered to the point taht it slowed the flwoering so it didnt' show hairs till the middle of the third week. I sprayed it with Milk in a spraybottle and damn no more mold or mildew on the leaves. luckily its still early in flowering, but its a fact it absorbs the mold/mildew. the leaves now have a white like dried elmers glue sitting on but not stuck to the leaves.

ya man, a buddy of mine had a bad leak on some water pipe in his house and everything would get infected until he fixed it.

i have a 3/4 bottle of "safer", and a full unopened bottle of some other crap sitting on my shelf for months. figure out the cause, then spray em down and it should be gone in a week. i had it bad all over the place, and now nada.

screw the guy at the hydro store... i called NPK industries directly(the makers of pmwash). according to them you should apply approx mid-late photoperiod when it is warmest and lowest humidity, raise your light(s) to the ceiling shut all of but 1. and then drench your plant, all parts of it to the point its literally flowing off. eg, when it says wash.. keep that in mind, they recommend you litterally WASH your plant with the stuff, this is why i say cost vs application is insane.. for a 3-4ft bushy plant, its going to take around 1L of pm wash to effectively wash it down.... they also say to do this to all plants at once in the grow room, not just the one affected. personally i think they need to rethink their buisness motto eg.. sell a machine that can make the wash from RO water, or significantly reduce the price per gallon of the product they are selling... after all its 99.9% water.
