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. 🙏

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?

I need help diagnosing what this was. I already cut off two of the affected leaves on the Kmintz, but other leaves have small amount of the same substance on both plants. The brown spot in the first pic ended up turning into a hole because it was so dry. Is this powdery mildew?

I'm starting to see some white spots on one of my plants and the bottom leaves are stating to yellow is it just fungus or potentially thrips? My other plant beside it doesn't seem to have to have the same white spots on it so I'm not sure if its spreadable.

White Spots on top of Leaves
I 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?

What are your best experiences for treating white powdery mildew? (4th week of flower)
I carefully removed all the leaves with WM on it, but i want to spray the leaves to hinder further development of the mildew. What are your best experiences? I've read about milk solution, maybe citric acid solution with a ph of 9? Can i spray the buds too? Thanks for your help!

Welcher Mangel ist das?
For about 10 days now, I've noticed that my leaves are getting brown spots. Unfortunately, these are becoming more and larger. Can I still actively counteract this? Furthermore, I see small white dots on the leaf surface. Are those salts?

Too little light
I 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.

mildiu polvoriento; tratamiento? sugerencias?
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 have been left with mildew, but I sprayed everything pretty well! I've only done it once, how should I proceed?
