Most, if not all the stuff you can do to improve yield is done in the vegetative or stretch phase. At this point the best you can do is to not be anxious and let the plant finish.
What you can do is to remember that the most weight gain happens in the final 2 weeks of flowering, so be sure not to harvest early.
She’s doing very well and you’ve done everything right to this point and seeing how that is the case your plant has everything it needs to maximize its genetic potential. If you were to add more than the plant needs you then it would take away from your yields at this point
Hit her with some Dragon force or a finisher and wait for her to finish up with a good flush other than that just ensure best conditions are maintaining
Hi,
You can get a SCROG net to space your colas out, this will definitely help get light through your canopy. My Gorilla glue grow yielded massively using that method, they were big plants with colas falling over by the end.
