Badass buddy!
If you could take a close picture of one of the leaves with the lights off we could give you a more definitive answer. If its the claw from too much nitrogen, the leaves will be dark green and glossy, its hard to tell if that is the case from the pic.
Also the claw usually goes from the top down where nute defic goes from the bottom up. If it is effecting the whole plant the same, it is probably an environmental issue like the RH u mentioned.
They defo look over ferted mate I'd flush heavily with water and just feed water for a few days
