Powdery Mildew
Hello all.
I've inherited an amazing thing - powdery mildew. A cutting I was given was apparently affected and now I've got in my flowering tent. All 6 plants are showing the start of the pandemic. So we are at week 1 after flip. I've just nuked the entire tent with neem oil.
Open to any advise and tricks to get rid of that nasty mildew. Help will be greatly appreciated

Re: Powdery Mildew
Baking Soda (sodium bicarbonate) -This is possibly the best known of the home-made, organic solutions for powdery mildew. Although studies indicate that baking soda alone is not all that effective, when combined with horticultural grade or dormant oil and liquid soap, efficacy is very good if applied in the early stages or before an outbreak occurs.

1 part Skim milk 9 parts water.
A tiny amount of soap (no detergent, no degreaser) and a little oil are supposed to help either of those stick to the plant better. I've never used either but most recipes use both.
If you were on this side of the pond I'd recommend Lost Coast plant therapy, but they don't ship to UK.

If you reduce the amount of hash you consume in order to preserve your glass you've missed the whole point.
The hash is more important than the glass.

Re: Powdery Mildew
either really low pH solution or really high pH solution.
old organic method is milk but i think thats to encourage lacto bacteria which produce h202 as part of their life cycle as well ass making pH of like 4 when in a concentrated formula like a LABs serum
