Is it normal?

[jlord20]

Good morning everyone, this is a seed of sweet mimosa (auto).
It isn't my First time with the germination phase but im scared about the yellow leafs.
This is the first day out from 2day in a dark area with 21-25 degrees.
Should i do something or just wait?
Thanks a lot for the help and any tips are appreciated.
Sorry for my English im italian

You need to put them in the soil right away. Those jiffy pots don't have any nutrients they are only for seed germination. That's why you see yellow. The long stem means you may need to add a little more light soon.
