Once you have it. It's hard to get rid of it. You can control it. Lower humidity to 45%. Mix up a gallon of water with a tablespoon of baking soda,1/4 cup of hydrogen peroxide 3% few drips of dish soap. Spray fan leaves. In the end you can do a bud wash. 5 gallons of water 1/2 cup of hydrogen peroxide. Soak buds with gentle wash. Do a double rinse of water and hang buds.

Homoginized milk mixed in water and sprayed on infected areas and around will keep it under control without harming anything

On my other grows I've had some issues with pests. The worst was white powdery mold, but I've also seen leaf miners, aphids etc. I want to treat this plant pre-emptively with something like BioNeem. Is it safe to do that at this stage of bloom? Can you recommend safe alternative

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?
