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.

how many times should we spray with milky water in case of powdery mildew when we are in bloom? do you have to spray with this solution every day?
Several people here advised me to dilute the milk spray with water, I did it, I diluted 400 ml of milk with 1200 ml of water, then I sprayed the plants in the tent, since they are grown in scrog, it is difficult to get everywhere.

Powdery mildew? is there an organic way to treat it? Milk? mild vinegar solution I have tried the milk spray. It may have knocked it back a little but i'm pulling leaves every day and keeping a close eye out for it.

White powder
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

Is this powdery mildew?
Is this powdery mildew? I am seeing some white spots starting to form on the underside and top side of lower fan leaves. Would adding an oscillating fan help prevent anymore white spots from appearing in the future or will I need to apply neem oil or something?

Does White Powdery Mildew brush off easily
Does white powdery mold brush off? Found some white stuff on my leaves but it easily came off with my finger or some water, its possible that the spots are minerals or something from my water or leftover nutes because I havent been able to get under theleaves to water.

PM or Nah?
Noticed some white spots on the tops of a few leaves. I’m days away from chopping and I’m wondering if it’s PM. If it is, what’s the best action to take at this point?

Leaves half white
So I changed the water and noticed these leaves changing color. It's like half leaves though...I'm not sure if this is anything to be concerned about? Would like to catch the problem before it becomes an issue... any thought?

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?

Ok folks, went out to check the trichomes and smelled something funny...like mold. Saw these spots on several leaves and now I'm panicking so close to harvest. Let me know what you think and what I can do about it, if anything. Thanks!!
