When I was doing LST, I would slowly train the main stalk/top down over the course of a couple of days once there were 4-5 nodes on the plant. After doing that, new tops would grow out of each node. Since the main top was bent down they would all grow back at the same heights. Once the new tops reach several nodes you could do it again if you want. I never bothered the fan leaves unless they looked like they were dying. I would prune those off once they yellowed.
