Very nice grow. Barney’s zkittlez Genetics stretch a lot so plants like this will respond well to LST. But any plants will respond well to LST as long as you have good pH, growing medium with the right nutes, temperature, and humidity.
Autos can be tricky. You need to estimate when they’re going to flower so you need to guesstimate on when you will top and have them recover well. Most I’d recommend is topping once and then LST right after. For autos, I usually top within about 2-3 weeks.
