HELP! Leaves on buds curling and Strange fur on leaves 5 weeks into flower

[9seccapri]

Hello there friends,
I was wondering if anyone had seen leaves like this before. I’m quite confused what the issue might be. When I saw the leaves curling I thought heat and light too close. The light was a bit close to the very top at 20” so I have come up to about 28”. Today I’ve noticed this strange fur looking stuff on the leaves and it appears to be getting worse.
Been in the coco/perlite mix all their lives and have be going great until recently. Any input would be greatly appreciated

Hello 9seccapri
almost 90f at the soil is probably going to be a heat problem. How hot is it at the top of the canopy?

I keep my soil temperature at 70f or below.

The top has been getting to 83f as summer here and my little air con is blowing into one of the side vents. I have a small desk fan tilted to blow the cool air up a bit. Perhaps I’ll stop that fan and try to cool the pots a bit? I’m in my last 3x3 grow before stepping up to a new, cooler tent.

I'm not sure what your talking about all I saw was tricholmes in the pictures under scope , it looks like the beginning of White powdery mildew, sorry for that news

What's your light schedule? High temps make all kinds of wierd things happen, but you got some revegg leaves mixed in there, almost like it's getting light leak or possibly just too much light

Light schedule has been on 12/12 for five weeks now. Didn’t see that at first but I could be the cause of the light leak. Had to open the room door a couple of times and the old tent is not what she used to be. I believe I’ve had my 630 watt CMH too close for a few weeks when then stretched. I did move it a week ago however the condition has not improved. I’m thinking I’ll dim the light to 400 until this clears up. I’ve since shown some leaves to a friend who believes it’s and aphid issue as she has seen it on her roses leaves. Perhaps the Sol Sense light is a bit much for a 3 x 3 also.

Lady bugs will take care of aphids, if you have them there is likely ants as well. Ants farm aphids,,, they will move them, milk them,,, much they same as we do with cattle.

Light issue. If you need to cool the tent down short term freeze a gallon of water then place near a fan. It'll drop your temps down from 90’s to mid 70’s for a few hours. Might be enough.
