Early Powdery mildew problem solution

[Bravo]

Hello guys ,
Im not a new in growing cannabis . I had this PM ages aho but it poped in late flower so i didnt do nothing .
But today as i was pruning the leaves before flipping , i noticed the begining of PM in one room , 38 plants . There was a lot of leaves to prune and i know i had to do more pruning in veg but it happened as it is .
So its just the beginning i took all the bad leaves and my question is what chemicals do you suggest is the best to spray ? I heard that there is something uou can pour in your tank also but i dont know what .
So any suggestions what to do ?
I dont want no milk or anything else

What are your temps and RH running? What are you using for airflow? Treating it is one thing, preventing it is the key.

I'd kill off the WPM before flipping to flower. I've used a solution of milk and water to treat WPM. It works well and recipes for it are easy to find.

For outdoor grows I have had good results by spraying about once a week alternating between a hydrogen peroxide solution and a baking soda solution. The solution strengths can be found online, can't remember off the top of my head. Have only used those outdoor though. Luckily I haven't had WPM indoors.

like i said from the 38 plants there was only aprox 20 leaves that had some signs , so thats why i flipped cause i thought its not a big prob.
And now tomorrow is the first day of flower so im going to do the sulphur spray i think

That's only necessary when using an oil-based solution without an emulsifier.
