Should be fine.
For the couple months before I bought a refractometer my hydrometer said my salinity as at 1.025. Then after the refractometer arrived, I tested the water and it was 1.019! Basically since I started my tank my salinity was that low and everything did fine.

You should be fine. Just make sure that when you raise it back up you do it slowly so you dont shock them.
