I think they could have been stressed enough to go male, who knows. It is only a theory. I am glad you got at least one female Emmie. That is what is truly important, not proving my theory right or wrong.... If the seed appearance thing works, that might be better anyway and I am experimenting with sprouting and identifying sex, not necessarily growing out, just experimenting. Not enough data yet to know with any confidence any truths.

EDIT: By the way, note how the red is so brilliant and it goes all the way around the leaf petiole? Might be a slight nute deficiency there.
