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!

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?

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.

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.

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?

Should I worry?
BBK #A2 has some sort of white substance growing on one of the leaves and is growing a bit deformed. Is this something to be worried about?

Spider mites?
My partner just cut some clones off of a pre-flowering plant & put them in a root rain spray cloned. Been 2 days since he cut the clones. No roots yet but he’s wondering if he has spider mites & if so what he should do. Do you all notice anything wrong?
