Jworjikstarted grow question 4 years ago I've been noticing some sort of white dust on the bottom leaves and stem.
I wiped them off with a kitchen towel with water 2 days ago, but i noticed today that they are back.
They look like cigarette aches. I'm not sure if it's powdery mildew.
I'm not sure it's visible in the pic
