Powdery mildew

Hey everyone growing outside and put my plants in a pop up green house the other week thought I had it vented good but noticed today white powdery mildew on a bunch of leaves... I was growing two plants and they were close together in my vegetable garden and got huge so not much light was getting to the middle.. I have a lot of flowers and sprayed it with a diluted soloution made for vegetables and fruits in bloom it is mostly made of sulfur... I pulled off all of the lower leaves which had it and a lot of the fan leaves to get light through the whole plant... I also took it out off pop up green house.. anything I should do or avoid ? I don't want to loose it now

These are them

the sufur will make your flowers taste funny, switch to flying skull nuke em it can be used right up until harvest and not effect flaver, also when you harvest you should dunk them in a h2o2 bath just incase. George Cervantes has a good YouTube vid on the bath

Thanks! Does it help to keep trimming leaves I see with it on ?

Its near impossible to get rid of it only control it. So no dont pull leaves then the plant has to deal with disease and regrowing leaves

There outside. Every time it rains, the plant is washed off..

First pic was sept 8 second one was yesterday I planted them to close together a lot of the leafs were touching in the middle and very little bud growth lots of flowers though...hopefully taking it out of green house and back into fresh air will help a lot...I know they said thining out large leaves can be bad because they are like solar panels and can put plant in shock but I'm in about week 5-6 of budding the hairs are starting to turn red from white and was told the plant won't try to regrow leaves because it is only concentrating on flowers now? I'm not going to take anymore off but hopefully I can manage for another 3 weeks without it getting ruined

I use Hydrogen peroxide and water, add a drop of dish soap as a sticker. Spray it real good... Seems to work.

Hard to get the greencure where I am in Canada grabbed natria product my local grow store had...the guy said he likes better than sm-90 have you guys tried either ? Thanks for all your input everyone

sm 90 is good. never used it for mildew just used it once for gnats

Green cure is bomb stuff, but Im sure any potassium bicarbonate will do. Gotta be careful & mindful with the stuff you spray on your plants though, even in veg. Lots of chemicals are systemic and remain in the plant for long periods of time. I believe SM-90 falls into this category? IIRC it has an exceptionally long "half life" to it, but I dont have any personal experience with it so if I'm wrong I'm sure someone will chime in.
I do have experience with Natria by Bayer and they make very good concentrated Neem oil. I would imagine their other products to be just as effective as the Neem oil I purchased.
