Hi, i depends on your preferences, how you lst. you should try both on different plants to see what you like.
you should wait a bit longer to start lst, because the branches are no branches atm. you won´t miss anything if you start a bit late, but you could stunt them by doing too much too early.
Maybue using a net to tie the branches down is something for you. i love it and i think its the best option for me.
Happy growing 👍
