Doesn't look like you went too crazy there. I did way worse...lol
I agree with southsacboy, it's the fan leaves that, through photosynthesis, crank out the flowers. No arguing that. But... I noticed that if you can get some light directly on the buds further in the canopy they seem to get denser, like the tops do. That density adds weight.
The thing is though, trimming too much in the bloom phase can cause stress that stunts (as it did in my case) and lessens potency, some would argue. Energy that could be used in flower making is gone to healing. So somewhere there has to be a balance. Trim enough to add some density, but try not to stress the girls. I have yet to find that sweet spot and so... now I tend not to trim at all past 4 weeks of flower and I LST instead. Maybe next round, I'll do one of each. Train one, lightly trim one, crazy trim another and see how they compare at the end.
