Anyone ever seen this?

Looks Good To Me. ^^

Always plant more seeds than you think you will need! This way you can choose only the best ones to grow on and also cover yourself in case there are any duds or germination failures.. As long as this seedling still has new leaves emerging from the centre, she should be just fine.

You can leave her grow ,looks bit off , if not sure ,get a new bean in the soil .

Might stunt its growth a bit but its not the end of its life yet. If you planted extra seeds to account for this. then you could cull it or give it away or transplant it outside someplace, If you did not, let it be and it will even its self out most likely. I don't think this is anything to worry about. in the future plan for seed variances and plant an extra 2-3 to help offset any potential loss. This is much easier to do with photoperiods as they can be transplanted and cloned so starting off in mini nursery pots does not take up as much room as a 3Gal auto pot. Good Luck!

Yep. Almost every seedling will give you a little stress with wavy leaves in the beginning. It's more common than not in my experience. What causes it, could just be a trait in seedlings development. It could be a pH it doesn't agree with. It could be environmental. It could be a oxygen issue at the roots. I see a touch of over water, which is super common with seedlings for so many growers. Keep that soil fluffy and on the dry side. Otherwise, it's likely nothing to worry about and as the plant matures it will go away.

Hi, it looks fine to me. Is your concern to have one big leaf instead of two? They seem quite separated to me. I would wait another week to see if it grows new leaves before throwing it away. Good luck with your grow 😎

She can grow, but u gonna get like 1/6 of the normal harvest.

Yes she will be lost, get her out and make space for the healthy plants. Nature is not prefect, not even cannabis.
