Those plants are looking better every time I see them. Good work, Mand!

Perhaps the one that produced a false female preflower was a gender bender? LoL. Whatever the case you did the right thing in ridding yourself of it. I don't know how you feel, but I always feel terrible killing off a plant I witnessed grow from seed, even a male one.

The remaining ones should fill out nicely -- looks like the one in the third picture is already on the ball.
