Incortect. Once an item as been upgraded it can be upgraded further. It will, however, appear grayed out in your upgrade menu if you either lack the skill, perk or mats. Obtain whichever of the prior mentioned you lack, and you shall be able to upgrade it further. It will always cost an extra mat. So if you're working on smithing, it would be better to wait until you can do everything at higher levels to begin upgrading. Othersie you'll spend, for example, one iron ore on an iron dagger for 'fine', anotther iron ore for 'superior', etc, etc.
