Powdery mildew third week of flower help I'm freaking out

[BiG $m0k3]

I had powdery mildew the first week of flour. Then washed it off with a solution of hydrogen peroxide and water which works great. it washed it off. Then I sprayed it with Silica Blast mixed with water because some guy on YouTube said that prevents the powdery mildew from being able to form on the leaves. But now a week and a half later the powdery mildew is back. Is it okay to spray with hydrogen peroxide and water again. it looks like little buds are starting to form already. I'm in the third week of flowering. I'm not going to spray the Silica Blast anymore cause that didn't help for shit. Thanks. Oh yea. I'm pretty sure the powdery mildew came from me not having a dehumidifier because my humidity is around 60. I'm getting a dehumidifier tomorrow to make sure this doesn't happen again. Could it come back again even with a dehumidifier?

spraying with goop is a bandaid over a festering wound,pardon the comparison,lower humidity to 30% or less,create positive fresh air flow around n over all sides of plants,high humidity and stale air creates the pm

Are you sure it's not just flour from the first week?

3 weeks in i would drench it with greencure and drop your humidity to 30%

if it doesnt come back you are blessed.

if it comes back at all trash the whole crop. or save yourself some time and just do that now

Most likely. If you actually see the pm on leaves the spores are flying everywhere in your area. Buy some green cure and spray them every week until the last few weeks of flower.

You need to lower humidity and get some air flow/exchange going ASAP.

Set off a few fungicide bombs before you try to run anything again in your room

Box fan on high and dehumidifier on 45%

Foliar feed a AACT tea, drop humidity.
