The leaves look like over water symptoms and possibly light burn. LEDs usually need to be further away due to how intense they are. 18-24 inches is what ive been told. Im thinking the roots do not have enough air flow but enough to still keep going. Step back on watering maybe just every 4-5 days. If you can I would go to the hydro store next grow and grab some air pots. Good luck with the grow homie!
