for sure, give it a go.
mutants are fun to watch grow when you flip em early like that, they get real weird lookin sometimes lol, i've had quite a few. one of those ace of spades plants that i posted was a mutant, now i can't tell the difference between the 2.
the sexing early is a nice way to see what the stretch is gonna be like too, that way you can trim/train it accordingly....and you'll know what size it should be when you flip it. like that GSOG i posted, that thing had a good 3x stretch to it, so i flipped it earlier than most so it doesnt take over my grow room.
