I keep it like the dude, In my grows these arms growing to big and healthy branches, i only bind them down ... they grow long and build a lot of flowers, I do it like, top after 4ths node , pulling the mainstem horizontal and binding down, and then binding the "arms down" so i have 4 colas with one topping. but you can do it as you want ....She grows very vigor and well i thin i would go with topping 2 times and further LST. and then let her grow when she reaches flowering( maybe until week 2 of flower then i leave her alone. And i dont defoilat or something on an autoflower, because her lifecircle s limited.
