Looks like you have some suspicious areas I would like close ups of if you can?
It’s the whiter shaded areas, that I think you’re referring to.
At first glance, there are a shit ton of trichomes, no doubt, but I don’t know if it’s the camera angle, or it’s actually shaded whitish.
40% RH is respectable. If you have a dehumidifier, I would drop that RH 10% or more if you can. With treatments and running my dehumidifier balls out, was how I ultimately solved my wpm issue.
Some growers will use peroxide and baking soda separately to treat wpm. Baking soda drops the ph on the leaves and makes wpm less desirable to grow on. I don’t know how much I believe that, but possible. Spores are always present, it’s the environment that ultimately prevents it from growing.
Correct. Peroxide is best, doesn’t leave a residue. But depending on the stage when applied, can stall flowering, it will turn your pistils brown a little earlier usual.
