I begin my LST when I have a mature 5th node, by tying down just under the fans of that node and pulling down the apical stem to appox. 80°(I get stem damage if I go further.)
As the stem adds nodes and turn up to the light, I move my tie down outward, tying down under the 6th, 7th, 8th and so on. As the axillary stems grow out from the base of the fan, I will restrain just under the bud site and pull down those stems, separating them around the pot to achieve the anatomy you see in the last picture. If fans are in the way, I pinch and bend. This is the method I settled on after trial and error.
