The story of how I went from 4 perfect mains to 3 is in the picture captions. I cut it down to 4 mains a couple days ago, trained them down with some wire and the next time I checked on them one of the branches had fallen off and was already wilted. Lesson learned is that I shouldn't try to do everything at once.
Since the symmetry is thrown off I won't worry too much about topping or training anymore. I'll let her bush a little then get her under a screen next week. I had wanted to train 2-4 main branches in each direction with the mainline, and flower with 2/3rds of the screen full, but now I think I will just fill the screen in veg. Still on the fence about that.
Nutrients are the same. Won't be changing that until I run into issues or the plant gets much thirstier, whichever comes first.
@chiefleaf55, Thanks! I've neglected to do a harvest tab but I should probably put one up just to put on bud pics. A lot of small but very sticky and lemony buds! high is nice too :)
