Is my LST relevant at this point of growth ?

The plant react to what you do in predictable ways.. the only concern is root structure.. as long as it is robust enough not to deteroy itself as you bend it down and add pressure to that area, then it is all good. An anchor at base of apical meristem is a good idea. give it support from the opposite side -- don't over do it or you add just as much stress pulling the other way, lol... try to even out the pressure from where you bent the top down to the opposite anchor side. you lower a terminal, it will cause auxiliary growth. you cut a terminal bud off, it causes redistribution of resources+growth elsewhere -- more so on the immediate branch below cut. Want somethign to grow faster? make it the tallest growth or at least higher than it was.. tie it up to opposite side branch and get them both going vertically.. they'll start to catch up. shape the plant.. manipulate it.. do as you want :) it will react in a consistent and predictable way once you observe it enough it's just clockwork to you.
