Low N?

started noticing some yellowing of the leaves, possible low N?
Let me know what y'all think.
She hasn't got her first dose of nutes yet, she's in a 1 gal pot, vegging under a 42 w 5500k cfl right now because alll the others I threw on my other baby in flower.

well naturally, that's the first sign to u that u need to start ur NPK nutes. Plant also could use a transplant to ur final flowering pot (either 3 or 5 gallon) depending on how much longer u will veg.

I was planning on start nutes tomorrow, just wanted to make sure it was a Nitrogen diffeciency first.
+ rep for the info.
