Leaf discoloration?

Any idea of what this is?

May be a genetic trait that duplicates on more leaves. If so, not an issue.

Did you splash any nutes on it. Looks a bit like what happened to me

No nutes yet. Looks genetic. Is there a name for it?

Early leaf set ... Ignore it ...

Once plant pushes into more mature growth , then can see if it is a problem on more leaves.
