Here, if I may say a few words about your picture.
The plant is progressing fine, but with every leaf tear you slow down its growth. LST means bending the plant from 2-3 "floors" and beyond. However, you also have the problem of soil in the jar, since the soil is not filled to the top, but there is 5-8 cm of empty space, for I don't know what reason, you don't even have room to fold it inside. By bending the plant and tying the fan leaves and the stem, you create space for small branches to grow without stress. Here is a small example of how to use LST to give the plant more light without tearing the fan leaves.
