That would still be ok. She isnt in flower or anything.id do the very low ones that really wont get any light. Also any little branches forming torward the center of the plant that arent going to stretch outward torwards the light.you probably could avoid some cutting to if the branches are still flexable and you could tie some away.i usually cut a lil less than half way up each stalk if its such a big plant and more in the center areas of the plant where some are stretching up but not gonna make it will provide air flow.
