I had the same thing, I have hard water and this white dust was from the humidifier. Try cleaning your humidifier (vinegar worked for me). I say this because I see the dust on your pot too.

Minor damage to a few leaves found today - what is it?I am trying to determine the cause of damage to a few leaves that was observed this week. It may be two different problems. On a few leaves, I see brown spots which may have originally been white. On another 2 leaves, I see a burn hole through the leaves with brown edges.

I have noticed small powdery mildew spots on my pineapple express plant. The soil usually feels pretty dry so i don't think it is due to overwatering. I put them inside at night due to humidity outside. Should I separate this plant from the rest?Week 7

WPMI found WPM on a few leaves. I was spraying spinosad at night. I stupidly thought spinosad would take care of that to. LED light showed much more PM but early stage. In A.M. sprayed 1tbsp baking soda, soap, veg oil per gal. Used 2 gallons. Will any of this interact? Thanks
