Welp. Time to hang it up

Could be light leaks as rock said. That'll do it.

I will also say that if you are running Co2, you should have heat in the low 80's, and very intense lighting. Otherwise they actually produce a poorer crop than if you had just drawn air through the room. Seriously they need TONS of light. I've seen this happen a couple times with people setting up sealed rooms.

It doesnt look like pest damage to me, sounds more environmental or genetic related... That's just my 2c.

How far along in flower would you keep those temps in the low 80’s? Also do you recommend running co2 throughout or cutting at a certain time during flower? Thanks
