Stab your self in the face with a soldering iron... its the easiest way.



srs, it keeps coming back... "killing it" is usually just killing the visible part, which is the spores, This will keep it from spreading... which is good.

Any time the environment is right, it will pop up again...
It like high humidity, large temperature changes, still air and dark.
Shaded areas will be prone to attack, as will areas up against walls or other obstacles to air flow. You want a fan moving the air in the room all the time, all the air...
EXCEPT WHEN YOU HAVE POWDERY MILDEW. Then you want to stop air flow as much as possible. The fluffy white powder is spores that can be disturbed and spread to other parts of the plant.

The safest thing to do is remove the infected area (Cutting off a bunch of leafs is hard... watching that shit spread all over is harder). If you leave the infected leafs it will pop up again when conditions become favorable, and then spread. It then becomes a balance between waiting until proper harvest time and managing the powdery mildew to save as much bud as you can.



Neem oil works to treat it, but strips trichomes off the leafs. There are a lot of treatments on google, its a fairly big problem... even outside the cannabis world.

 

a friend of mine showed me this stuff: Actinovate cost under 20 bucks.
ACTINOVATE | Organic Fungicide | Stops Disease | Safe for Pets, People and the Environment | Natural Industries, Inc.

I bought it at orchard cuz I had some powdery mildew at 5 weeks on a past grow, I only sprayed the effected leaves and it seemed to work. luckily no mildew on buds.
