I'm wondering what kind of mix you are using in your pots where you would have a neutral pH? Most mixes have a bunch of peat moss or similar stuff. Peat moss quite acidic. Are you using soil in your pots? If you are using some sort of commercial potting mix, or some homemade stuff that's a lot of peat moss or pine fines, it's hard to imagine a non acidic pH.
Not sure what method you are using to test the pH, but very often the test strips or the meters are inaccurate.
Either way, neutral is OK. When you pot up, if you use pine fines or peat moss, you'll have a mix with a lower pH for next time.
I wouldn't recommend using soil in your pots, if that's what you are doing.
