I've been having this problem for bit now but its usually one or two fan leaves. It's getting worst, so of course I did some research and it only confused me even more lol. I'm growing in foxfarm coco loco, watering twice a day with FF Cal-Mag (5ml), FF Grow Big (10ml) and FF Big bloom (10ml). PPM's are 650-750, 10% runoff. I did a slurry test and got a ph reading of 5.8 and 120 ppm. The light were about 24 inches away from plant but i raised to about 32 inches this morning. She's going into flower tomorrow. Any comments would be greatly appreciated.
Could be broad mites, high temps., and/or large rH differences. Also overwatering.
1. Get a microscope and scope it out very carefully for broad or russet mites
2. Check rooms Relative Humidity
3. Verify dry rates; soil moisture and watering cycle (runoff is good but need to know dry rates to avoid over watering)
Just a bit of heat / light stress. Are you watering coco loco as you would straight coco, keeping it soaked all the time? I didn't know you could do that. I water as I would soil and have excellent results.

Plants with damaged roots due to overwatering cant take up enough water so they get easily stressed. Watering twice a day in cocoloco sounds scary to me. How big are the containers? Do you have lots of gnats?

I guess I'll cut back on watering plus my RH has been all over the place. I plumbed my dehumidifier so from now own I'll be getting a steady 40-50% RH.
I’ve been watering twice a day at 650-750 and this morning I did a slurry test, I got 120ppm also the ph was 5.8. The nutes coco loco came with are long gone...
