Just went through you pics, really nice grow. Hard to believe they filled out the whole tent. Buds where looking thick and tight/sticky.
I personally would have 4 plants in that same area and use much less soil/nutes/labor, and produce same amount or more.
I know plenty growers like your self prefer same method you apply, but it's just not for me. But I do have 2 tents so I veg while the others are in bloom. Last harvest off 4 plants under 1 600hps was 23oz. I was very proud.
Now I am organic so I will have to see where my yields go.
