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?

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!

Gold Leaf #1. Potential Mold?
Gold leaf #1 has developed a white substance on one of its seed leaves. Can anyone tell me what this is, and if I need to do anything to combat it it necessary? Going to let the Gold Leaf dry a little bit (no water) over the next 24 hours and see if that helps.

When using a Apple cider vinegar/water mixture is it ok to spray the entire plant, leaves bud and all to combat Powdery Mildew (PM)? I’m assuming it’s ok and may help prevent the PM from infecting the buds leading to bud rot?

White powdery mildew in late flower
What's your best remedy to remove it on flowering plants? I just found it after I had forgotten to replace on of the fans when I left them for a few days. What can I do to remove it as quickly as possible without ruining the buds? I'd prefer not spraying them with milk.
