At this point you don't really want to do any defol. If you have to, wait til the stretch is done. Then I would only tuck them under during flower. If you have to defol, just do selective leafs to open up light to bud sites.
Some will take the lower fans off after stretch, but I couldn't tell you if there was a benefit or not doing it that way.
