Problem with clones

What could be the cause of these slightly yellow leaves! I cloned these about 2 weeks ago in a aero cloner! They were transplanted in solo cups about 5 days ago! It seems the leaves are starting to yellow I know for a fact my soil is high in n! Could this maybe be a calcium problem just starting? Or maybe is it just the plant transitioning to the soil?

This is normal in my eyes...
Maybe they're scavenging P for root growth?

Just transitioning, they look fine.

Just don't go trying to "fix" them till they get into larger pots in a week or 2.
