That is too late in flower to take clones successfully.
-rot in the bud due to high humidity
-additional stress as the plant senses its life is ending-I doubt they will even really root, just croak.

Better off to reveg and take clones after.

BTW for everyone who wanted to know what the best cloning medium is, that pic shows rapid rooters and they rock my sox. My cloning setup is identical except thqt i use a heat mat under.
