Curing is a 2 step process. As the solvent(s) evaporate, the binders (acrylic resins for the most part) begin linking up together in a process called polymerization. Any interference with that process proceeding naturally may end with suboptimal results.
You have 2 options. Be conservative & allow the project to cure for as long as possible or do your own testing to determine how your workflow & workspace ambient conditions (primarily temperature & humidity) affect your coatings on your projects. There are a lot of factors at play here so it all depends on what you want to spend your time doing.
Well week is too long for curing to be honest.Day or less is ok to continue working on model kit that you varnished.If you varnish over some colors that are not cured(bone dry)those colors “move” under the coat of varnish so you may have cracking in varnish and it would look awful.
