nah, after the first 4-8 new colas from fimming(do you know what fimming is?) I dont really prune for new colas too often, lst doesnt hurt the plant and makes it more manageable and you can keep the canopy at the same height meaning the tops are all getting optimal lighting and your not wasting any of it almost, when i prune I'll tie down the 2 new growth shoots after they emerge and grow a bit. I keep canopy at the same height till flower, that way they all get the hormone that tells a growth shoot its the main one instead of only the highest parts of the plants so you'll get a canopy of awesome big solid top cola nugs..
