This is a soil grow room temp 64* humidity 58* 3rd week of 12/12 Skunk#1. I saw the white spots and they are almost like salt, grainy more so than a powder. No harm to the plants so far. I saw pics of powdery mildew but that doesn't look right and the temp and humidity are low. I've looked over pics I can find but nothing yet.
