let it grow lateral for atleast another week then you can think of letting it grow upwards or if the plant is healthy and not started to show pre flowers by next week then you can go for 1 more round of topping for 8 mainsSo, I pulled the two largest fan leaves and I retied the four mains. (I also watched all five parts of dubxxl's vids) ..Since I'm only going for these four mains, does that mean that I just let each of them grow upwards from here? Also, it looks like I have a fifth main happening. One of the four chutes has another coming off of it. I won't be able to grab a photo until tomorrow.
(upload a pic you might have Fimed one of the tops accedentally)
