I've been there! Couldn't wait to let it all ripen as I had to flip the room so it all got chopped and kiefed. Thats a lot of kief.
Ever since I have been ruthless with that lower growth; I leave a canopy of 10-12 inches and everything else gets pinched. All the way through flower I look out for new shoots / tiny flowers popping and I remove.
On a 5x5 scrog with 4 plants this works pretty well.
