Is this mold?
DrBinocanswered grow question 6y ago
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.

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?

Too little lightI have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.6y ago

Powdery Mildew near end of floweringFor 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?

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

Mildiu polvoriento, sugerencias de como seguir?I have 4 autos 1 week away from harvest, I have a slight powdery mildew, I’ve cut the affected leaves and sprayed with 1 part milk and 9 parts water. I'm sure some leaves must still have mildew, but I sprayed everything pretty well! I've only done it once, how should I proceed?

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.

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

White powderI'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

White Spots on top of LeavesI have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?
