half looks done half doesnt

The upper half of my plant is damn near ready,rockhard nugs.The lower half has alot of white still and is still pretty airy.If i chop the ripe upper half and leave the bottom half will the buds harden up or am i just wasting time??

ive read here that people cut the good buds off and let the others finish.. I have the same problem, most of the top colas are good but 4 on the bottom are like if they were in the first 3 weeks of flowering

Prune the top leaves in a spiral stairway fashion. It will open your canapy for the buds down below. Cutting the good ones and leaving the others will work. Stronger lights could also help. These methods have worked for me.
