Hey man, the plants are looking great so far. As for your LST, the reason people do LST is for the plant to cover a larger horizontal area instead of growing straight towards the light so that as much branches / budsites as possible get as much light as possible. Therefore you also want all of them to be the same size to spread the light equally. I let my first quick one grow without any training, it got 64cm tall and took 13 weeks to finish with 13,5g dry bud even though I broke stems, encountered a serious Nitrogen toxicity and I had a shitty 20W blurple china LED.
So, in short: Your plants look great and healthy, and the LST you did looks good aswell - just dont let go of it ;) Keep on bending the tallest branches down (CAREFUL and only 45° at once per day per branch) so you have an almost even canopy when the stretch is finished (in about 7 - 10 days). Other than that, expect branches to grow about 40cm-45cm tall (with bending). And remember that this plant is bred specifically for beginners and is extremely resistant, even I didnt manage to kill it back then ;P
Hope I could help, if you have any other questions feel free to PM me :)
