powdery mildew help/qestion

Hello, i had an issue where i found powdery mildew in my grow room. I had treated the plants with eagle 20. I plan on making them sit in grow for a min of 4 months then they will have 3 months for flower. I also plan on having my stuff tested to make sure that there is nothing on it after harvest for my safety.

Anyway, i guess i am now in attack mode trying to make sure that i dont get that shit again, i have dehumidifies running 24/7 flower at 40% humidity and grow around 45-50% humidity. I also have a mini-split ac unit keeping temps under control, 75f in grow and about 83-85f in flower (w/co2).

So my concern now is that i been seeing little white spots on the leafs in my grow room on some plants here and there, now im not sure if its powdery mildew or if it could be dried water spots from watering or if from the leafs sweating or when they breath out moister. What is the best way to tell the difference so im not picking off leafs for no reason.

Pm will wipe off. Also if you hold the leaf at different angles under the light you can get better views. It sucks I ve been dealing with it a while now. Eagle 20 sucks to spray too! I've used lots of it. I m having good success with green cure. But to much and it burns your pistils. Good luck!

if you have PM on your flowers it is unsmokable. it hurts but tear it out and move to strains that dont get PM. otherwise you will chase the issue forever.
