  1. Can i spray it on buds? Should i rinse it off or just spray plant and leave it? Will it fight pm over time or just on contact as it washes it off? Useing a water hydrogen peroxide mix with a touch of orange dish soap safe for veggies now; its working ok to wash em off but the pm comes back 2-4 days later. Will k bicarbonate work better? I am a little afraid of it since i mixed a spoon in a gallon of ph-ed water and it permanently through the ph way off.

Citric acid is probably the best natural fungicide around. Also I suggest adding 3 mils glycerol/glycerin (same thing different name) to the water, since it increases growth according to at least one study I read. Haven't tried it yet myself, just read it yesterday and don't have any on hand right now. The study showed very impressive growth enhancement though, usually about 50-100%. They only tried it on a few plants but one was spearmint, which is fairly similar to weed, being a leafy flowering herb. However it does tend to attract moisture so it may not be appropriate in your case. But maybe after you fix your humidity and ventilation problems. It might be okay with the citric acid also in the spray though. Hard to say.

Its supposed to throw the ph, that is how it works to stop pm. You'll have to keep spraying all the way until harvest whether you use h2o2 or the k.
