Hi
@Undercovergrower! If it's your first time with autos, you might consider letting the plant grow in its natural shape with no HST operations such as topping or fimming. LST works well with autos but HST manipulations usually stunt the growth for a week or more. Remember with autos, loosing time is loosing yield. However if you're confident about this and if you're not hurry to smoke your buds, you can try to top her at the 3rd node after the 4th node has developed. This way, you loose a part of the plant, but the recovery / new growth happens much faster. Hope this will help, keep us up-to-date and happy growing 👊
