Hello HairyBeastsGarden, your girl is looking good.
LST is to my opinion one of the best training methods you can use because u can shape the plant to your desire while training so you catch 2 birds with one stone.
U can start lst as long as your roots are established and the stems and branches are thick enough to bend without breaking them.
I would recommend bending the main stem to the level of the other buds so they can all grow a little bit more even.
Hope this was an helpfull comment.
Keep on growing my friend. Peace 👍
