You are growing a very fast developing plant that will go to great pengths to flower - as it grows so fast, the rings (like cable ties or something) will just either cut into the stem as it expands or it will just fatten around it, if the stem has already reached max thickness it aint gonna do squat.
Your best bet is now either trying to gently develop LST over several days - go GENTLE as branches will be getting woody and will be harder to manipulate just try to spread them and control tueir stretch, otherwise you can slowly and gently try to get a 90o bend in the stem without splitting it.
If you were growing a tree over 50 years then it would be a difference.
