Agree with
@HeaveyHittah, need to support the base of the plant in the opposite direction of the LST. I attempted LST on my plants with this grow and it slightly pulled up the base, most notable in week 9 day 63 "both" picture where if you zoom in you can see the jiffy pellet is slightly pulled up. Big fan of LST after this grow, really helped to keep my canopy even and I can see the benefits moving forward. Best of luck to you!
