Harvest top half early?

[Blunted]

My lady is about 5 ft and a week away from harvest. She has many branches and i was wondering If I should harvest the top half, drop the light and continue flowering the bottom half? The bottom half doesn't look near as developed as the top and I want to increase my yield as much as possible. Thanks for the help, and yeah I plan on LSTing my next grow.

It's up to the grower and that's you. We never trim any branches. When she's ready to come down we take the entire plant.
