I would try and use LST before defoliating an auto, The lower yield is not worth it. Other option could be to try and bend some of the leaves out of the way without fully removing them. Granted an ultra conservative defoliation could work just for a few sites on the plant if you feel its warranted.
Best Of Luck!
