Leave them. That's what grows into colas. I have been making the mistake of removing most of them and I hurt my yields by doing it. Once they get to the size you want them, then I would look at removing a few nodes here and there. I just tied mine again and they're coming along nicely. Should be done growing them wide in a week or 2 and then I can work on height. I tried to group the pictures together, there's 2 pictures of 2 different plants. Been removing the big fan leaves as they grow to focus more energy to the bud sites and help promote faster growth. Seems to be working pretty well so far. They look good though, I wish mine were that big already.
