Hi homie ! You can use Bordeaux mixture (copper sulfate plus lime) it is the better non chemical fungicide I know ! Anf if you want to use Neem oil the better recipe against mildew is : sodium bicarbonate (2gr5 / rainwater) + Neem oil (a teaspoon) ! And I don't recommend you to go chemical , your harvast is soon and you don't want to smoke anything esle but weed ! I hope It will help you , hit me fore more "grand mother" recipes/tips ! :grinning::+1:

Go lower with humidity and get one more fan what directly hit the canopy
Cut the infected buds carefully away
Hope you get them healthy

Spraying with neem oil should help. Good luck! :+1:

Hi @ThatGuyWhoFishes! You can use a wet tissue/paper to clean as many leaves as you can, then mix organic apple-cider-vinegar with tap water, and use it as a foliar spray. Neem-oil can also help stopping & preventing powdery mildew (few drops of neem oil with water as a foliar spray) and it's also a good way to prevent from any pest invasion. If none of these "DIY" solution show quick results, I'd use LeafCoat from Biobizz, it works great for this kind of issue. Finally, make sure your air-flow is OK, judging by the number of plants in this room I'd use at least 2 fans, gently blowing onto the canopy. Hope this helps, keep us up-to-date and happy growing :facepunch:
