Blueberry auto mutated?? To keep or to rip??

Have a blueberry auto that's 13 days and is still quite small in size to others at 2 weeks old,anyways was wondering if I should keep or rip and start over with this grow,will she even be okay if I left it???

It's fine. Let it do its thing. Some start slower than others. Some are bigger, some smaller. You don't know what you have unless you grow it out.

It doesn't look mutated to me.
It looks like it may have been topped either by you or bug chopped off the top.
Like Hawg Wild said, it's fine, some plants take off faster than others and if it was topped it could have stunted it for a few days which is normal.
A few things that can stunt a plant for a few days when it's in the seedling stage are topping, low amount of light and low temperatures especially if its warm during the day and cold at night.
when it takes off and really starts growing it'll take off like a weed.
honestly I think your seedling looks pretty good.
Just my 2 cents.
