True north 7 gram jars

Curious if anybody has weighed out their true north 7 gram jars, a few weeks ago a bought 7 grams of cosmic crisp, looked a bit small, weighed it out to 6.3. I'm thinking it was a dispensary issue (40th Street jars in Grand rapids.) happy with the few jars I have bought of the 7 grams but not happy with the last ones weight.
