Lowryder x NYC diesel Auto Fem

So I got 3 lowryder x NYC diesel Auto Fem seeds from attitude seeds, they have been going for about a month now outdoors. One was much bigger then the other two, almost 3x as big and very stretched out, also the buds look stretched out as well. I have been keeping a close eye on it, and last night it hermed out on me, big balls on the steam. I pulled it out right away. Anyway this is my first time with auto's and with femmed seeds, dose this happen a lot with femmed seeds? or with auto's? I was thinking next time i will just get the reg. Auto's and not femmed. On the bright side other two plants are lookin like champs.

It's funny but I've been kinda noticing when one plant looks or smells a lot different than the others, they seem to go hermie. I know there are different phenos but it seems to be going that way for me :/
