I realize this post is old but I wanted to pip in anyways.
the best way I have found to increase yeild is LST. "Low stress training" You should look into it! Especially with healthy looking plants/indica dom. plants like yours. It is the same concept as SCROG except you are bending the plant's shoots and tying it down to the pot it is in to create and even canopy. The advantage of this as opposed to SGROG is that you can continue to spread your plant in flower and you can rotate the individual plants throughout the flower cycle. I drill holes all around the side of my pots and use pipe cleaners to tie down the stems as even as I can. The most important thing in flower development is getting light directly to your bud sites. This is why lower branches produce smaller buds, less light. But if you can create a plant who has all bud sites recieving the same amount of light you could have 6 mains colas instead of 1. 4 ounces per plant, instead of 2. you know?
Especially if you are growing only a few plants at a time it is a great way optimize your results.
