Please help! What is going on with the leaf structure of my 12 day old plant?

Can anyone tell me why the leaves of my plant are not symmetrically growing and why there are 5 on the top? And also they don't look like the first set of true leaves. They don't have the typical shape of a cannabis plant.

Thanks for your advice!

Odd looking plant. Definitely a photoperiod leaf. Is there any other node development under that top lead?

Yes there is, see on the picture. What should I do, wait and see?
