The harmonic series is a law of physics, but the actual pitches produced by a vibrating body are affected by the qualities and imperfections in the body.
The clarinet is the poster child for this, since as a stopped cylinder, it only produces the odd overtones. Another example is the trumpet, where it’s difficult to produce the fundamental. Overtones can be flat or sharp for various reasons. Some overtones are stronger than others in certain bodies, this is what gives instruments their unique timbre.
The series is G, G, D, G, B, D, F, A, or on the clarinet G, D, B, F. So you are probably getting an “F”, but it’s flat. This isn’t surprising when you think about how bad intonation can be on the regular scale/fingerings. I think that particular overtone (the seventh overtone) also “out of tune” or flat to western scales - they always have it in parentheses.
The B is harder to get than the F.
It’s easier for me to think about it as a string, because you can see the whole number relationships.
