Northern lights auto 2nd attempt

heat stress does this as does light stress in my experience. May need to fix the temps and back the light off a bit. Good Luck!

I've got no idea what it was but a few leaves showed up with holes. A couple of small ones and some longer. Some see through spots showed up too so reckon there was defo something munching away in there. I've sprayed down both sides with a pest controller and defoliated the worst affected. Seems to have worked so far!
