Try to get on the inside and take some of the small stuff out that won’t get light. Someone else mentioned that also. If you want to increase yield that’s where I’d start. Build a cage around those come time when they bud they won’t have to work so hard to stay up/prevent early breakage and more energy will go into bud production. Those things are good sized btw...
in my opinion, which is very limited in outdoor environments I will admit, is to do what is said above ^^^. A slight defoliation, as it doesn't do as much outdoors as inside; given your garden seems to get amble sunlight over a good coverage of your plants.
Did you top your plants during veg?
if so,
I would definitely build some sort of SCROG (screen of green) setup as well.
It's a little late for the full deal if you didn't top at least once, some of these things will need to start being fully implemented on your next run, but I think some chicken wire surely couldn't hurt anything to keep those buds from weighing down.
This being said, your garden is seriously gorgeous. An amazing space capable of enormous output. If you didn't "top" the girls, (a quick google on topping cannabis if you're unfamiliar will get you right up to speed),
definitely definitely do! also get a 2 stage trellis system, using chicken wire as you'll be outdoors. Depending on genetics as many have said, you will have some enormous water bottled sized colas possible in that garden.
One love man. Keep rocking that beautiful space.
