I had that Flower mutation... on my Fast Eddy Grow. And i did not treat her different than the other Plants. in the end her Top was as big as a Fist ( after 9 weeks)and it was time to harvest. I think on a fotoperiod you see it better . In my experience its no problem to let hr grow. i just would watch the Rh in the late flower, because its growing so dense , there may be the danger of molding. happy ( Polyploid)-Growing
