hi bro , you have high humidity in tent , drop humitity under 55-60% for day and night. it is a mold that appears on the leaves when the humidity is too high and the ventilation in the tent is low. Increases ventilation and decreases humidity. 🙏

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?

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

Powdery Mildew near end of flowering
For the last few days, powdery mildew is starting to form on the leaves and some of the buds. I've cut where mildew was, lowered humidity to around 45% and increased air circulation by focusing a fan on the plant but it is still forming. Anything else I should do?

Is this powdery mildew?
I just noticed this tiny white spot on a leaf of two different plants and having trouble ID’ing it. It doesn’t seem powdery or fuzzy and almost looks like a mineral deposit… but I really have no clue. Appreciate any ideas—thanks!

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.

Possible mold/mildew - I ask a ton of grow questions but figure someone else might learn if I do well or f up. Good community here
Mildew? This has been on certain leaves of my plants since I got them so I didn't think much of them. But as I'm about two weeks into flowering, I want to see if this is possibly an issue. Have okay airflow in the tent but could be better. Humidity is 55% atmosphere. Thoughts?
