You might calibrate the TX Gain. But it should not have changed this
quickly. Odd.
Others will have advice too.

I immediately noticed that the Power Out bar graph was peaking only
around 60-70W. It normally peaked closer to full output on voice
peaks. Later I checked it with CW and it was still only hitting about
75% output. I confirmed the power control was set to 100W. I did an
Auto tune before each test and this problem exists on every band. Both
my LP-100 and my LP-100A digital watt meters showed about 120W output
(both were factory calibrated by Larry). But the K3 bar graph still
shows 25% lower than full output. This I also confirmed into a dummy
load. I had not observed this before Sunday. All else appears to be
functioning properly.

Is this a known indication of an upcoming problem, or do I simply need
to recalibrate the K3's Power Out meter?
