These are under 1000w LED lights, with both veg and bloom settings on a 12/12 rotation. Literally just use NY tap water I let sit for at least 24 hrs first. Medium is Coco husk/ miracle grow 50/50 mixture ( I know, I know bad choice), fans and a ventilator. This is happening both to my plant in veg stage and the one in bloom. Please help!
I’d check for bugs. Looks like Spider mites
Check the underside of the leaves with a loupe or magnifier.
Barring that take a pic with your phone and zoom in.
On it. Thanks so much!!
