Powdery mildew during flower Help!

can anyone give me tips on getting rid of PM during g flower growing outdoor ive tried apple cider vinegar 2tsp and a quart of water didn't seem to work and was also told 3:1 ratio but that seems to strong i tried it on couple leafs it seemed to work but is it bad to spray on the buds? I've tried white wash which works but its so expensive and need to spray it everyday any other tips?

you can try a 40% milk and 60% water spray. look up sodium/potassium bicarbonate spray

yinegar is an acid, you want a base to get rid of it

I sprayed potassium bicarbonate on my last remaining plant today outside. Raining out now. How often can you spray it on plants?

every day in growth, not sure about doing it toooften during flowering, poyassium or sodium bicarb buildup on the buds

just found this, may be of use A silica spray might work for you, Dont ph it down or anything like that, you want that high ph to kill the pm

Where you get it from? I'm pretty late in flower think less then a month till harvest its my first grow im in Chilliwack bc Canada had a rain and wind storm since monday ends tomorrow had to put all my plants under my patio but then sunny all week

I also on one bud found a brown spot guessing bud rot do I cut that spot out or the whole bud has to go ? Its a big bud hope can save it

Nvm had to cut few buds on one plant have to inspect it better during the day fuck that sucks its just on one side on the tops of couple buds hope wasnt the apple cider vinegar that caused it just started using it 2 days ago luckily this rain ends tonight and its sunny all week start tomorrow

Hodgey I just picked up a bottle of Dr Zymes Eliminator. I haven't used it yet but its suppose to dissolve PM and spores.

You can use either a base or an acid. Both a high and low pH can kill PM. The reason that most use a base with a higher pH is because it's much easier to burn your plants using an acid. But vinegar has been used for years to control PM. The acetic acid is what kills the PM.

I've been spraying a potassium silicate solution in my garden and outdoor cannabis plant with great success. It's kept it off my vegetables and roses which always get hit hard this time of year. It's had no ill effect on my cannabis which shows no signs of PM.
