Big Bud Possible Powdery Mildew

[Ottcanuk]

Hey everyone. Looks like i may have some mildew here. Can someone comment on the image below? Humidity is quite high right now at about 75% but temperature is just under 80, seldom get's over 82 or 83. This does easily wipe off but doesn't seem to smell at all. Any help appreciated. Btw, i have another plant in close proximity, different strain (G13xBlack Widow) and it's fine. Also, this plant is in week 4 of flower.

Thanks!

Thanks for the replies.

Brainthor, mine don't really look like the pics in that link. Also, lower branches seem fine, this seems to be just upper leaves.

One+one, i haven't sprayed this girl with anything except ph balanced water, although right now i'm trying hi ph (8.5) spray in case this is mildew.

Thanks!

I have suffered from the pm many times.In your situation I don,t think it is the prob.PM seems to start where the leaves come off the branch,whereas yours is centered on the leaf.Seems to me that something got splashed on your plant.Keep an eye on it and if indeed it is PM then you will know in a matter of a few days.It spreads like wildfire once it takes hold.I will say a prayer for your plants.
good luck

Well everyone, was definately PM. The good news is i seem to have totally eradicated it with 2 treatments of 3% H2O2 foliar spray. I'll probably give them one more spraying in a day of 2 to make sure. Also running a dehumifier now.

day or 2?? keep doing it for a week or longer to make sure you got it. don't back off PM as it'll stick around even after full scale war on it.
