I’ve been battling the PM since my last run, I fill a spray bottle with 1 part 3%
hydrogen peroxide, 3 parts water. I’ve tried multiple solutions best I’ve found is turn your lights down to like 10%, then I spray them about 1/2 hour before lights out, by the time the lights shut off for the night they are usually dry if your fans are blowing on them correctly, then I set the lig back to my previous set point so when the lights come back on all is normal
Repeat the spray every 2 days until it goes away, then I mix 1 gallon water to 1 tablespoon baking soda and a drop of dish soap and soak the leaves down,
It took about 2 weeks until I’m now seeing no PM, the peroxide sprays kills the PM (but never all of it), the baking soda spray changes the PH of the leaf surface to where it is unsuitable for the PM to grow
Been doing some reading in PM, My newest countermeasure attempt to just keep the PM away is to give it UV treatments, PM’s DNA is safe and protected when the blue wavelength is detected at sun up, but at nighttime that protection turns off, UV only can alter and Kill the PM’s DNA, so I have some UV/IR light bars coming that fit my light and I’ll have them stay on for 1/2 hour after my main lights shut off as the treatment is best followed by at least 4 hours of darkness
