Maybe. It’s difficult to determine CG location based off trim without first knowing your wing and stab incidences are. Example, if your stab is at zero incidence and your wing is between zero to 2 degrees positive, then I would agree that your CG is a bit forward. If your stab has some positive incidence then the up trim could be to compensate for that. Another tell would be the landing. A nose heavy airplane will want to land fast and require lots of up elevator.
