Yes you have to bend down the top again and again and again. it will grow up all the time. Plants grow into light and with gravitation. Bending her doesnt stress really stress her, so do as much as you can early, before the stem becomes unbendable. Also bend they leafs into the back or to the sides, otherwise your LST is useless, since you can see by yourself your new growth is getting shadowed by the leaf. I wouldnt cut it tho, bending is key.
You can also PN me, i can manage the progress a bit every few days.
