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.

I've had issues with PM in the past. Safers brand 3 in 1 seems to work temporarily but it always comes back. Also seems like it may deteriorate the trichomes on a flowering plant. RH 50% I currently am using a worm casting foliar spray and all is staying well. Any more tips?

Welcher Mangel ist das?
Seit etwa 10 Tagen zeichnet sich ab, dass meine Blätter braune Flecken bekommen. Diese werden leider immer mehr und größer. Kann ich jetzt noch aktiv gegensteuern? Des Weiteren erkenne ich kleine weiße Punkte auf der blattoberfläche. Sind das Salze?

Pollen sacks or powdery mildew?
I noticed what I thought was powdery mildew on a leaf, then noticed funny looking things right next to the powder. I think these are pollen sacks, and if they are I want to know if anything is recoverable, or if I need to scrap the whole plant/grow. "Second Grow" on my profile

Is this powdery mildew?
Could this be powdery mildew on the pictures? I have to add that the spots were a little more fluffy but I removed some of it with my finger. The weather has been really dry, so I thought it was impossible, but it still looks like it. If it is powdery mildew, what should I do?
