No, No, No, No don't defoliate autoflowers, they're not meant be be stressed like that, you're doing exactly what you're supposed to be doing stretching it out to the side with LST and letting the light in...If you defoliate and it takes 3 days to recover that's 3 days lost productive growth, defoliation is meant for photo period plants which have ample time to recover, same reason you don't top a autoflower...It's counter productive, if someone defoliated a auto like a photoperiod 2 weeks before flower and 7,14, 21 days after flowers, that would be 12 counter productive days recouping, not worth it...
