Ok first Off i just want to say good job she looks beautiful. Second I see three things you can do:
1. you could add another tube at 3000k for more light because in the flowering cycle you need more light in the red zone because your plant is begging for it. The flowering cycle uses up a ton of energy but not if it does not have enough light, water, or air/co2.
2. You could cover the room in mylar and increase the use of your lights. I see your walls are bright white and yes that helps but not as much as mylar. Mylar reflects 95% of light.
3. You might want to add a small co2 genorater something like a fermenting yeast setup.
I thingk these 3 things will help you have a great harvest. Personaly, I would do all 3. (Dont forget, the more lumens in the red are you have in the harvest the more compact your buds will be.)
TIP: this is a newish thing going around but if you want to increase the potency of the tricromes on the plant or in simple term s make that shit dank go to your local pet store and pick up a reptile light with uvb light in it. Trust me! Have the light on the plant (not to close) for 4-5 hours each day in the middle of the day (do not be in the room while it is on). The reaction between uvb and the tricromes will help it reach greatness.
