Some Yellowing - Normal, Fill in the blank?

hey all. i am 21 days into flower with a chemdawg going inside. i am pretty happy with how she is looking except for a little yellowing down the bottom. usually this doesn't worry me when later in bloom, but it's creeped up the plant a bit and it seems a little early in bloom to be creeping up.. no?



reading up on it i am in a toss up between a nitrogen deficiency due to normal plant maturity or the possibility of excess nitrogen. i mean the top looks pretty green, not pale by any stretch, but there's some minor clawing and the creeping up of the yellow which could fit the bill even though i don't believe i've overdone it with nitrogen.



i've on been using a base nute - gh maxigrow dry. total cumulative of 2.5 tsps so far into grow. using promix hp with added perlite and that's it.

environmentals have been consistent running between 70-82f with a medium to high rH.

so, nothing to see here move along or something to address?

thanks for the help..

I wouldn't stress it mate, looks normal and healthy.

Edit - I debated on saying maybe add a little more nitrogen but that late in flower I'd be very reluctant to

Its not too much N. move along

Ahh trying to diagnose an issue. I would say root bound!!
