Adding nitrogen during late flower

This is an auto crossing white widow and sour diesel and she’s over 6 weeks in flower (not exactly sure) and lately she’s been very yellow.
Looks like nitrogen deficiency but I hear they can get yellow like this with a few weeks left to harvest.
I’ve given a little boost of nitrogen but it’s making no difference
Any ideas?

Forgot to mention using promix with heavy 16 nutes and growers choice LEDs at full blast lol

I just have to say, that is a hell of a plant.

Lol it was a free seed I almost want gonna keep

Too late to mess with more N. Huge plant which required huge feeds.

just keep what you’re doing.

The plant will lose leaves until it’s matched your N input.

Is your plant greener down below? N def starts bottom up

A lot of bottom leaves turned yellow and fell off thats why I thought it was an N deficiency.I was considering bumping up the bloom nutes since I’m only at half str but it might be too close to harvest lol not sure yet

I listened to this the other day. I didn't know any of the stuff about calcium or mineral uptake.
