flat G note

Hello,
I have a problem with Howard D chanter and Howard reed that is on extended loan. The upper octave especially the A is sharp by about 30 cents. In the low octave the A is fine but the G is flat 30 cents. I’m sure this is a reed problem and not the chanter as it was playing well a few weeks ago.
Same reed too :confused:

Any suggestions would be appreciated.
