No, the thing is about Auto's is, everything you do will slow them down or stunt their growth when it comes to high stress, cutting, transplanting, etc. In this particular case, I highly recommend doing some LST and tying down some of the branches to expose some of the growth you wish to be exposed, later on, once they have sexed and started to bud, you can then trim the lower junk a bit, just don't go nuts and try to trim over several days to reduce shock.
** and or what namvet said lol.. tucking as well is a great LST technique. Tuck first, tie if they won't stay tucked. Just be gentle.
