What the fornication happened?!

I finally harvested. I harvested blue widow, white widow, lsd, and super lemon haze. I trimmed up the widows and it seems fine. I tried the haze too. It's fine too. But the fucking lsd hermied I think! What the fuck happened?! There is no male flower in sight. But every cola has a seed or two. Is this normal? Thanks.

it happens... when a male flower has finished spreading the love it usually falls off ... i pretty much live by using dutch master "reverse"... even if the plants hermie no seeds develop. i love the stuff
