Leaves/Bud going very dark color

Is this normal? First grow and plant is 7 weeks into flower

yeah, that's pretty normal. that can be genetic, or caused by cold temps at night. it usually happens around the middle of flower if it's going to.
nice looking plant, only real criticism i can offer is you went a little heavy on the N, back off next run and you'll see the difference.

I removed the N weeks back and the glossy dark green hasn't faded. I was using the wrong ferts for the first few weeks of flower. Anything else that could be causing it or do the leaves no revert back?

Temps have dropped a bit recently so I'm guessing that is it. Anything bad, should I be making the room warmer at night? I'm hitting about 67F night and 77 f during the day

nah, if it drops much lower than 60 at night it will slow down ripening, but 65-70 at night is fine.
