Grow back it does, at a surprising rate. I’d suggest you cut out shoots as you plan, but don’t defoliate the tops you keep.
I tried taking about 1/3rd of the fan leaves to thin it out my first grow about 3 weeks into flower. . It responded by stopping flower development and growing new leaves.
My theory this go round is to leave space between the colas so they don’t block each other, and let the colas I’m keeping get a good 6 inches above the screen before I flip to flower.
Literally every node will try to become a branch if it acts like mine does.
