First clone & greenhouse grow

Hi so an update for week 2. The fish mix and bio - grow are working wonders! I saw speedy growth from the previous week. The leaves grew into hand size leaves and the plants got much taller. I actually transplanted some smaller extra clones that also took off and added some @DYNOMYCO in the mix when up=potting. Attached are some pictures of my first time LSTing. I kept like 4 out of the 10 of which i will try top 2 and keep 2 natural. I have tied the main stems of the clones (which don't have parrarel nodes and i'm unsure how to top them because of that - help pls) down to the sides of my fabric pots. As this was my first time doing so I wasn't sure how much to bend and if I bent them too much or too little and if there is a "correct" direction to bend them in. Let me know. Otherwise things are cooking in the greenhouse. DYNOMYCO is fueling my roots and my rhizosphere is pumping. The growing conditions seem ideal for my plants and they are happy. I just hope my LST didn't do any damage to them. Do i ever undo the ties later on in the grow?
