Heavy Nitrogen deprivation in late flower?

Hello everyone, i wanted to ask the expert people
there, about one thing I've been thinking lately.
We are talking about mineral nutrients, hydroponics or coco..
I usually follow a mirate feeding plan for the needings of the plant during the whole flowering process, meaning that nitrogen and EC levels are progressively lowered after peak flowering, around week 5 (at that time i give nearly as much nitrogen as potassium, 3/4 N to K rate).

Around week 7 to 8, ppms are brought down to 400-200, npk 1-2-3 or so..
I start flushing about one week prior to harvest with zero ppms, but i never get fully faded plants this way.

Plants need N thorough the whole flowering process, but if the plant at peak flowering is leafy, green and massive shouldn't the stored N be enough to last until is completely absorbed?
So do you think that should i nearly fully remove nitrogen feeding after a certain point of flowering, in order to get faded plants at the end?
Thank you for any answer!

Thanks everyone! What you said makes a lot of sense.
Didn't want to bring in the flush-non flush debate, as i never really flushed or got yellowing plants by the end of flower but still got amazing tasting buds pretty much everytime, with non organic nutes.
As said before was just wondering to give a try to the real flushing concept, instead of the usual ec decreasing and a single week of r/o water..
if i think about it, the majority of the Nitrogen seems to stay in the leaves that will be trimmed, swollen calyxes stay light green even with dark leaves..
So i agree with you that I wont probably obtain any smoother taste, but just less potency and everything..
I'll stick to the usual method!

Npk 123 is not starving plants of nitrogen, use the proper fertilizer if you want nitrogen deficiency, reducing a 123 is all deficiency not just nitrogen.

Pk 023 will.
