Hey guys I came home from work and immediately checked on the girls. When I opened up the tent and started looking at them I noticed what appears to be powdery mildew on two of them. The 11 roses and the northern lights. The the other three are clean and looking great. My humidity is in the range of 64-71% temperature has been 71-86 degrees. Two days after feeding the temp outside temp was 90 degrees and the tent got up to 90percent when I was at work came home and immediatly got it down to 60%. Will a spike for 10rs cause the mildew..

What I have done before is use a fork like a Pitch fork and just turn the top layer and then crumble it up. Probably with the heat and humidity, that may have done it. Turn the dirt, do not water yet. Do a 12 on 12 off and check ur dirt tomorrow.

Wow, I did screw up and Im sorry and glad bill came in. I had to go back and reread. Man I was thinking you meant "White fuzz on top of the dirt"
Flower I like my vpd about 1.3 I believe.

Around there with lots of air circulation.

I will when I get home from work.. are there any products u recommend
Lots of Homemade remedies work well. I've never worried about RH during Veg. I've had it as low as 25% & as high as 80% without an issue. Flower is a different story. I keep it under 40% during Flower.

If you can see it, it has been growing there for a while already. Don't assume the other plants are clear just because you cannot see the mildew yet. I recommend treating all of the plants, not just the ones with visible mold.
