She started flowering about 5 days ago and already built up quite some bulk. Also, she nearly doubled in hight. I have trouble trying LST with her, because the branches are very strong and I'm afraid to break them. So I just cleared up some space by removing big leaves and added tab water this week.
Colours are perfect again. The bio tabs seem to do their work. Still wish I had a bigger pot; even though it's an Auto, I think it would have been benefecial for her.
