I bought a clone the other day that may have had some powdery mildew on it. I didn't even bring it in my grow room and I have noticed this white dust on a couple of my plants. What should I do? Ive never had it before. I am four weeks into flower! See pictures(sorry for the blurple). It is in the low center below the gnome.

Well I already hit it with some peroxide water mix so it won't show up now. I am hoping that takes care of it.

Sounds like you got it.

Temp, RH and airflow? Do you have the ability to drop RH and up the airflow? If not, you may need to defoliate some.

I have an AC/Heat/Dehumidifier in the room. I can set it to remove some humidity. I seems to stay about 50% to 60% humidity. I didn't think that was too much. I can add some more fans.

When you have PM, sometimes you have to make changes beyond what is normal range to keep it at bay.

Once it is on your plants, you will never get it all until you harvest and sterilize.

But you are right, this cultivar must be sensitive to PM because your setpoints are what I would expect at this point.

Also up your cleanliness game - wear gloves when working on the plants and wash up good before and after. Do whatever you can to minimize spread via farmer contact.
