Mutant seedling, no new growth.

This bagseed sprouted around 3 days ago and it appears to have only 1 cotyledon , and the first true spiky leave is rounded in shape and i can't see any new growth coming from the stem. Thoughts?

Give it about a week for new growth if nothing by then Id toss it.

Def. a mutant though, I have a strange mutant right now only shooting one fingered leaves yet its the fastest growing plant I have. Maybe you'll get lucky but it takes awhile for seedlings to start the new nodes at times.

Don't act differently ! Traitment should the same for all and she will be just fine after some time
