You can start LST even earlier than where you are at now, I would say start some LST but be gentle with the Stem as the plant has some size to it already and is not as flexible anymore as maybe 1 week ago.
Take your time, bend the stem slowly and with care. Re adjust training every 2-3 days .
I ran the same strain recently, did some LST to it as well, beautiful strain that creates a lot of trichomes ! good luck with your grow and training đŞ
