Asking?: does the root system mostly form during the veg cycle?...which would mean, it be a waste of time to transplant to a larger pot...after flowering cycle has started?

Opinions requested. Bottomline, veg longer, more roots=bigger plants?...more yield?
The roots will continue to grow until the plant is finished. Remember that as long as the plant is getting bigger, so are the roots.
