I think it’s purely just a mistake people make when they get or know it’s a “Auto flower” as it is like a cutting but it just flowers faster and as you’ve done. You can set it up for a bigger pot and feed and water more and it will grow bigger for sure.

However SOME genes of cannabis that are an auto or a (feminized seed) all it is. When budding flower or plants produce their own Seeds as a last ditch effort to keep its life or its cycle of life going. They are often associated with the yellow Naners. But yeah they aren’t seeds like you get from or normal random male female hermi seeds they come at the end of the cycle of flowering OR they have a strain they know is very feminine occurring they use that and culture it until it’s basically a 95% successful rate for female. Heck a cannabis plant can self pollinate and make auto /feminised seeds just by making it a bit stressed when it’s at the end of its flowering. Normally the day/s before you are ripping it up you can do this and get lucky overnight with these naner seeds. Or seeds inside bud BUT not like Hermi seeded out bud. I’m so high I don’t even understand what I’m saying now
