MarcXLanswered grow question 6 years ago the LST isn´t the problem now. For me it seems you sent your plant into flower too early. After sending her into flower growth is mostly stopping, now i see the flowering stretch but she won´t get much more higher from now on, maybe 10 or 20 cm.
If you do lst, give your plants 2 more vegetation weeks before starting bloom. So you train her into your desired direction, let her sit one extra week to concentrate her on growing towards the sun and then switch to bloom.
That´s what I do when i do LST.
