Thats a dificult question... i would start slowly in spreading the Mainbranches and bend them spreaded. your goal is to help the light to get everywhere. So there is no " iron Rule" how to do LST. Look at your Plant follow her and look wich direction she wants to go at all, bend the branch ( softly) and bind it. But i wont do it way longer than second day of flower... So next time you planing Lst.. start in around week 3
