Almost exactly what I do.
I don't like early yellowing
But I don't mind them fading towards the bitter end.
In fact some of my best resin production has been on faded plants.
I know that is not science but it happened.
My gut feeling is that restricting food
Towards the end may shock the plants into survival mode so they shift into high gear with the resin.
Again that is just something I think MIGHT happen.
You could be right.
I've finished both ways but never actually done a side-by-side bud comparison.
The ideal nute schedule seems to vary by strain.
I've had strains that would puff up if you gave them nitrogen during flower but other strains did just fine.
I ran a Cindy99 clone in my last crop that ended up with puffy buds but the double purple doja finished great. The were in identical grow bags, same soil, same nutes.
Both had been grown out successfully by experienced growers (good genetics).
I'm not sure starving plants of nitrogen actually reduces it in the final product because N is mobile and buds are the #1 priority for the plant.
