Sickstring,

Your looking good, I wish I read this earlier, I would have said just do LST. I also use MG moisture control and a few things to be aware of is watch your soil ph. It has a tendancy to rise over time from nute and salts buildup. I counter this by watering with water and nute mixes adjusted a ph of 6 to 6.5.

Back to LST here is a current pic of a mature plant that was LSTed. This should give you an idea what LST will do. I only LST no FIM or topping.
