trichomes.color

This is a 10-11 week old THC Bomb auto its my first grow and cant tell if it looks done any help would be much appreciated pictures where taken all over the plant Thank you

Someone said that their trichomes look darker on the top buds,as opposed to still clear on the lower buds. Is there any advantage to cutting the top and letting the lower buds get more light (and grow larger). Or should they all change at the same time...
