Looks like heat stress. Not 100% sure on that though... wait for more replies and opinions.

It’s Russet mites.
No bugs were seen with my microscope.

I'd treat for russets/broad mites anyway. would only take a day or two after a micronized sulfur spray to find out if it was mites or not, and a bottle of sulfur is like $10.
I checked another leaf and found no insects. If I find a russet infestation I will remove the affected plants. No one I know has successfully treated for those , not saying it is impossible. Just that I will do what I can to mitigate further damage in the other plants. This is only my 5th outdoor grow, but my mentors have decades of indoor and outdoor experience. I usually lose a plant or 2 a year, as Oklahoma has every disease, pest and fungus known to man. Part of the game is figuring out what strains thrive here. If I see leaf septoria the sulfur will be coming out in a heart beat! Thanks for the advice! I had not heard of sulfur as a treatment for russets.

Not always, the most obvious symptom is the new growth looking just like yours does. Russets are extremely easy to eradicate with wettable sulfur.
Thanks! My friends have always seen the mites under the microscope when that has happened to them. I still haven't found any bugs under the microscope after 3 tries. I'm wondering if it is a virus at this point. Or a root disease picked up after these were put outside over the last 3 weeks. Only the 2 phenos of this same strain are doing this. And we have had some hot days. 97 a couple of times. Some of the leaves seem a bit improved, in the cooler recent weather.

Hey pal, any update on what your issue wAs? I’m having what looks like the exact same problem. I’m on my second run of organic no till in 30 gal pots outdoors and two 15 gal pots that I made up soil for this year. I was wondering if it’s strain related because four of my five are the same strain that are showing this issue

The plant that had the most issues has resolved whatever the problem was. The other plant still has a little leaf distortion, no big deal though. I think it was some kind of PH issue. My plants are in the ground. My best guess on your plants is a small amount of heat issues. Are your pots insulated and mulched?

Would you say it took about a month for your plants to recover? I'm up against something very similar.. seems to have affected my entire garden to varying degrees (outdoor grow). I suspected heat stress/lack of water for awhile but this started 3-4 weeks ago and my plants are yet to bounce back (see: attached). Your newest growth with the glossy leaves, etc looked very familiar. I'm attempting to treat suspected broad mites with Azamax but I'm afraid I'm losing hope. Glad I stumbled upon your post. Any sense of what a bad infestation will do to finished product? Does it basically become unusable? Thanks for your time..

Edit: If its not Russet/broad mites then >I would look up leaf hopper virus if its been going on that long, Also look at BCTV in Cannabis
Do you have a microscope? If you have mites you will see them, but you need a microscope. Are you in pots? How big are they? How hot is it there? I am in the ground and I think I had some ph issues, which worked themselves out. Took at least a month.

I have a microscope, yea. I spotted two mites on two separate occasions and what I assume are their eggs but neither resembled broad mites (or broad mite eggs). I'm in raised/terraced beds comprised of topsoil (w/ heavy clay), cow manure, sifted compost, and a bit of peat moss. My pH wasn't crazy when I tested it.. 6-7 or thereabouts? I'm in an extreme Upper Midwest location.. ag zone 3a-3b. Although we've seen some unusually high temps for our region coupled with moderate drought conditions. I've sprayed Azamax twice in the last 4 nites, once combined with an insecticidal soap. I also just ordered some micronized sulfur which I hope arrives in time to apply at least once prior to flowering. I also ordered some neem oil but I'm not sure I'll be able to apply both the sulfur and neem before flower because I'm learning that sulfur can't be applied within approx 2 weeks of any oil-based product. Got a preference betw the two if I felt like I only had time for one before they move into flower? Also, while I have your ear, what do you know about mites life cycle(s)? Should I consider moving my grow next year? Do mites live in the soil?
I don't know much about mites. Never really had them to my knowledge. Hopefully some of your plants make. My biggest issues outdoors have been leaf septoria, which is fungal in nature, brown spots on leaves which then yellow and fall off. Maybe your plants can still produce? Have you read up on cannabis viral issues? All I can say is just keep going and see what you can learn from the experience. Note which strains deal better with your area and focus on those for future grows. Like all plants, some just do better than others in certain regions. I always lose parts of plants and even whole plants every year. Outdoor growing is brutal where I live! I have been using sulfur, because it helps prevent more septoria formation, but I should have started spraying in June instead of July. The only other thing I really apply is Zerotol for PM in flower. I get stem borers and grasshoppers and bud worms and leaf hoppers, but I don't spray for those, as they don't really destroy that much. I just keep looking for strains that deal with insects and molds , better than others. One of the best outdoor strains I have found is Mandelbrot's Royal Kush. Good luck!
