hey there Dana, you want to start LST around end of week 2, it's never to early, but after a while it's too late because the stems and stalks get too brittle. hope this helps ! 🚀
Hi! I would do it at the third/fifth knot since it's the best time to start modeling the shape. Since it's an auto I would only do an LST without topping or fimming that could possibly stun the plant. If you're planning to top and LST a future feminized plant you should do it at the fifth knot, not before.
Stay safe and happy growing 😉
When it's about 3 weeks old usually and grown 5 nodes about 15cm tall.
Then secure the stem in place on one side of the pot and bend the top of the stem and secure to the opposite side of the pot. After a few days all the under growth will be shooting up.
