Corn fields are nuted heavy early and when they get to their flower stage the nuting is over. Is a corn stalk brown or green when you harvest?
It uses the leaves as fuel when the roots are empty. That's why they yellow. How close do you manicure? It would make a difference only when you don't manicure close and did not flush. The remaining single and small leaves would hold the excess nutes and affect the taste of the bud.
As the leaves are used as fuel and die, the plant is programmed to give it one last try to be fertilized and throws all the trichs it can in case a stray male pollen is anywhere in the area. About 2 weeks before the cut, I stick thumb tacks in the stem and braches, I twist the plant heavy, I raise and lower the lights too close and too far away. I call it purposeful stress. You do it the last two weeks to avioid the stress having time to hermie the plant (which is also a last ditch effort to survive - no male pollen around, I'll make my own). I've tried it with and without the stress on the same strain and with produced more trichs and slightly bigger bud.
