There is always a balance. One thing to keep in mind though, is that small corrections early on can prevent big problems later. I've seen multiple times where a person was not corrected for what at the time seemed like minor annoyances, but they led to big issues and terminations later. The old adage comes to mind, "it's not what you say, but what you tolerate". If you communicate a reasonably good standard early on, it is helpful for the entire team.
