Should empty field captions be specific or generic?

I have an app with basic user profile fields editing functionality. Each field presents the field name, the field value, and an edit button (e.g a pencil).

My question regards what I display on those fields when they haven't been filled in yet. I don't care about the exact text inside, but I do care whether this text will be specific for each field or generic.

Example (specific empty field captions):

Name:    No name specified yet     ✎
Age:     No age specified yet      ✎
Address: No address specified yet  ✎

Example (generic empty field captions):

Name:    Not specified yet         ✎
Age:     Not specified yet         ✎
Address: Not specified yet         ✎

Which one is preferable and why?
