Yepppers! You could also LST the taller ones (Tie down the main stem with bread ties) to the edge of the pot (drill holes) and pull those branches down gently cause you might break one. Dont worry cause a bandaid and a matchstick can heal any broke stem.

Now you have plants the same canopy height and maybe you heavily increased your yeild by the LST. Sounds like a win win.

Now you can flower with the canopy all at the same height.:thumbsup:
