40 parts homoginized milk to 60 parts water spray affected area and repeat as necessary at lights out or near sundown. If your growing inside then lower your humidity. Cheers

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!

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!!

Powdery spots on leaves
Noticed powdery spots on some leaves this week (week 23-24). Plant is over 10 ft tall. Only fed water and got plenty of sun. What should I do to ensure a healthy harvest?

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.

Is this powdery mildew? How can we know for sure?
Could these white spots be mildew? We could easily just basically shake them off, without any residue remaining. Currently only discovered in those two spots seen on the picture. In pics I find from mildew, it usually starts more dusty.. I also made one picture under the micro.

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?
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?
