Hi there SHS, yeah i tried topping and not topping, topping really works if you don t stress your plant out too much and do some useful training on them. Autos stress easily, even transplanting to bigger pots stunts them a little ! If you're going to top them wait as long as possible usually until the bottom of week 3, then proceed with training as you normally would. Often you see folks top too early, dont be that guy ;-) hope this helps ! 🚀
