What's going on with these autos?

Dude, kill that last plant, get it the fuck away from there right now. It's a hermi, the worst.

At first, I’ve thought you might have stunted your plant by nuking it with heavy amounts of nutrients. But absolutely not, looking at your diary the plant was not delayed. It isn’t your fault, you did nothing wrong. These strains are not stable, proof is the hermaphrodite. If you got them on 2fast4buds.com, I’m sure @Fast_Buds can do something about it and replace these seeds, plus some extra seeds and some goodies for the inconvenience 😉

That last plant looks male. Your plants flowering stage still seem to be on the early side. It will still grow bigger. “If its a male plant I recommend getting it out of that environment. (Depending if you can come up with a use for it) Even if its a bit early don't turn on them. Let them do there thing and learn from the experience. I’m sure they will turn out just fine. Good luck

It's on age bro. They flower around about 5 weeks no matter the size
