Look. Ill admit my clones are only young. But since the 3rd bend I feel like they have stopped growing I mean, from the top. The but points are moving along but the top of my plant I feel like it has just stopped. And I have only just reached the side of my pot?!? What the fuck. I still have the circumference to go. Under a 400w hps. Organic grow. Hoooooowwwwww loooonggggg.??? Jeez Louise I want to flower. I'm running out. Fast.
If you bend the top lower than any of the side branches, growth of that main stem will be limited. By LST'ing you are distributing the plants growth hormones to what the plant now thinks is the top (e.g. anything that is above the main cola). If you want the top to grow longer let it start growing unimpaired and tie down those side branches.
