It would be a crime to not process the trimmings from this plant One of those smaller leaves has more trichomes than a whole bag of outdoor you get from a dealer
Not specifically time in veg, but I stripped them before moving to the new space, which if I would have done after moving, would have not chopped so much. So then I had to let veg a little longer, but node spacing was terrible, but plant was too big to veg much more, so I flipped.
Light levels are always monitored closely. Light leak, entirely possible! Nutes, pH, could be better.
It looks like a awesome pheno you have. I would say your issue is ether a light leak or insufficient light. It has nothing to do with your vege time. If you are in your grow space after lights out it needs to be so dark that you loose your balance. You will be astonished how a light leak can screw with your bud development..
