Late stage nitrogen question

[Gardinhackle]

Just a quick question regarding nitrogen. I am in week six of flower, outdoor grow in pots, photoperiod plants, using "Advanced nutrients" - "Bloom" and "Micro" so nitrogen is very low now.

My lower fan leaves are going yellow and dying which I assume is the plant up-taking the nutes from them, is normal or should be upping my nitrogen again?

Thanks in advance
Hackle!

Plants need just about as much N in flower as they do in veg. Check out my post here for the charts and numbers for veg and harvest.

Awesome! Thanks @InTheShed

magnesium deficiency, and plants assimilate 80% of the nitrogen they need in veg,

WHAT your seeing is like i said, a magnesium deficiency.

notice how all bloom formulas are lower in nitrogen?

use half as much, but keep doin what your doin and add magnesium

when the plants energy needs are the highest, its need for phosphorous and magnesium are highest

A magnesium deficiency typically presents with intervein yellowing and then rust spots. I'm not seeing anything like that on the OP's plant.
