Prognosis of mistakes and where to go

The best thing you can do is just wait and see if its going to make it. If you have other seeds or clones ready to go and could use that space it might be a better option. But if you want to try and keep that little auto flower going it may surprise you or it may just turn out small and be a runt. I'd leave it, grow it out with the others, pay close attention to it as more stress can sometimes lead to hermi traits, aka nanners don't want that to pollinate the tent. Making these mistakes is what will make you a better grower. Good Luck and Happy Growing.
