Too much N-
. Look under the leaves

I would stop fertilizing it during it's next watering, I grew a normal bag seed plant before had that happen, just used plain water and it slowly came back to life, but maybe it was just the strain I grew, it didn't look like that strain.

New growth is always lighter than the old, that''s natural. What are the ppm of your nutes? it looks like it might be too strong cut back on the strength.

yup your right to much N as for heat he is in perfect temp condition
I used to believe and kept temps to 76 degrees a real dialed in room lights on and 68 off but found with some experiments that running hotter temps was better also implementing 4 day feed schedule day 1 feed day 2 foilage spray just water day 3 water day 4 feed and accomplished pound per plant i dialed in temps to 86 - 88 lights on and 68 lights off bud development was trifold averaging 9 to 18 grams per bud dry
how many of you walk into a green house ????? hot as fck but plants are wicked

I think way over nute, also have you checked under the leaves with a microsope to see if you have spider mites??
