@captain Lucky, super cropping is the way to go, Or give her her own tent and pull all the branches apart and to the same height.
GT is a huge producer and would happily fill that tent alone.
If she were mine, I'd still remove a lot more of the lower growth and be trying to get all the tops at the same height by super cropping(it's a daily core).
She has many more weeks to go yet and, within reason, whatever you remove now will still be made up for by the extra weight you'll grain in the main colas. When I grew hybrids indoors I would stop removing growth after about 3 weeks of 12/12, but with Sats continuing to grow during flowering it's not such an issue.
Continue to feed lightly until she is flowering really hard.
Just my two penny worth; others more knowledgeable might say different.
