sorry for the super late update guys, but I will say how I combatted powdery mildew (with success, and some big disappointment)
so I mixed like 1-2 drops normal everyday detergent soap with 1-2 teaspoons of cold pressed neem oil. it did a fantastic job paired with lady bugs. however I will say one thing, I experienced heavy weight loss from this.
the heavy amounts of oil (1-2 teaspoons in a regular spray bottle) mixed with 1-2 drops of soap definitely made my plants growth inhibited. there are buds on some plants that are more mature then others where I did not spray them. next time if I have this problem, I am going to cutback on my sprays and include non detergent soap.
I’ll upload pics here shortly to show the deformities in my plants from this treatment.
