It’s hard to get rid of once you have it so now you need to combat it the best you can but it will be an up hill battle for sure. Your environment isn’t optimal if you’re having this issue. Several things come to mind with PM like stated above what is your RH?
also what are your temp swings like?
Also do you have good air flow around the plants?

what helped me the most was getting my day & night temp swings under control with an ink-bird and a small space heater.
I know I don’t have good air flow because I don’t use any fans inside my tent just a 6” exhaust blower with an open 6” port with passive air flow but my temp swings are very minimal. Best of luck

That is a bad time for PM. Remove all infected leaves (spray with water first to reduce spread of spores while cutting off leaves) and get them out of the grow space.

Bleach the tent or room. Get a filter, be it furnace, panty hose, whatever you can find to filter the incoming air. Increase airflow into the grow and the plants. Spray plants with high pH water daily until harvest. Make sure plenty of air circulation and spray water as lights come on.

Remove any leaves that show spots before they get worse and just treat with water until harvest.

How do I get rid of powdery mildew while in flower?
.

Potasium bicarbonate spray will change the ph of the leaf/flower so the powdery mildew can't grow there.

Regalia will boost the plant's immune system and help the plants get over the pm.

A post harvest bath in a citric acid solution will eat away the pm.

An AIRRos system will put out reactive oxygen species that will kill the pm in the air and on surfaces.

If you don't have any potasium bicarbonate try a milk and water solution (1:10) saturating both sides of the leaves, flowers and stems.

.

All of the above won't help until you get your environment down.

Perhaps you'll end up smoking buds frosted with PM.

What I ended up doing is figuring out the condition that allowed PM to thrive in my plastic environment. Once I tackled that vector PM hasn't been back.

There's something about leaving the milk in the sun for a few hours to get the enzymes going before you spray.... Obv not cook it but something about the sunlight... Can't remember exactly will have to look it up

Milk works great on my squash and cucumber plants outdoors. Never tried it indoors, something about sour milk smell in my grow space doesn't do anything for me.

This might sound funny but apparently it’s an option for gardeners …..

Urine Helps Fight Fungus In Your Garden

Plants can develop fungal diseases such as leaf rot and downy mildew. Uric acid works great for eliminating and discouraging fungi on plants. Dilute your pee by about 50%, then use a spray bottle to spritz your urine on the affected areas !

It will kill Downy / Powdery mildew / leaf rot and actually helps in composting soils. It will kill both Erysiphe and Sphaerotheca species.

A garlic / water spray is another garden option.

When's the latest you can spray for Powdery Mildew using Athena IPM ? Does PM turn into bud rot or what happens to the bud, if I only see it on a few leaves?

Once you get PM is it like in the clones forever or what?

when you finish growing dunk it in h2o2 water then h2o2 and then water and dry it should remove most of it but will remove taste and smell. called water cure
Can't I just remove the leafs with PM on them after I cut it down? What does PM look on buds, does it just sit on the outside of the buds or does it get inside the buds?

PM gets everywhere. And it'll thicken as time goes on.

looks like a tiny hair under a microscope and as it gets older you have more and more of them that it takes over the bud.usually starts in parts that are deep inside where its hard to see soo i wouldnt fuck with it.i personally would make some oil and not even try to smoke that. even better would be to trow it away but you probably wasted half a year growing and dont want to soo do what you need.

I just cut the plant down and I only seen PM on maybe 1/3 of the leaves and it wasn't much PM on the leaves. I cut many of the leaves off.. How long before the PM gets inside the Buds? This plant is a horrible yielder and has very very small buds. Can I wash the plant tommorrow or what?
