Its only wrong if they do not need it. After you water the pots lift them and remember how heavy they feel. Then when you lift them again later, they should feel much lighter. Then water.
Or you can watch them close and wait for them wilt abit, then water. That should give you hint at how many days inbetween waterings. Just water one day sooner than it took them wilt. It wont stay the same through the entire grow but will give you some marks to go by.
