OK I had a really good look on a better screen now. From the first pic, I can count nine shoots I would have removed. At a rough count and keeping in mind I am missing many, I counted 13 bud-bearing shoots. If you look at the top view, I would say about 7 healthy colas are on that plant.
Ideally, those 7 colas should have been the only 'branches' on this plant. Unless you have severe PAR, one of the reasons I am considering LED now, I have seen how many more fat shoots enough LED can grow... Either that or a whole stack of HPS... This guy on BreedBay stacked 9 HPS fixtures into an 8x8 tent. In that case, every shoot is pretty fat, you should see that flower room OMG.
But anyway, compare profile view to top view, keeping in mind the shoot-count, you will see exactly how much bud is shaded quite badly. What happens is the buds in good light supply the energy for the shaded buds to grow, so neither perform well. A plant really suffers on yields this way. I also learned the hard way.
Me and you running layman's rigs not involving many thousands of watts, efficiency is everything. Basically, a bushy type that gets topped tends to waste a lot as it keeps bushing out. Remember the real goal is more main colas, not more shoots overall.
I really feel dialing her in is going to be a cinch. It is really going to be all about those shoots. This is what Gen meant with 'buds needed more room to fill out', each branch should look like a plant spaced close to another plant (branch), spacing is similar to a tight SoG. I opened up my Cornerstone a bit last night, I will try get some good pics for you at lights on...
