Seedling with weird looking leaves

[LeonardLunte]

It looks like something took a bite out of it lol, really thin too. Does somebody know what this is? Possibly a mutation? Compared to other seedlings it looks very abnormal to me. This is my first grow so Im sorry if this is a dumb question...

this is day 5 btw

Hi Leonard, welcome! One of my seedlings looks exactly the same as yours in the pic above. I thought maybe the leaves are different because its the only sativa dominant plant I have (the rest are indica). Not sure if this is true though, maybe someone can clarify this hypothesis? Good luck bud!
