Shade effect on series panels.
Pictured below is the shading on 2 of 6 series-connected panels: And this is what the controller says: So, 57.2 x 5.6 = 320w (IN) Normal (full sun) should be about 84 x 7.5 = 630w,...

The OPs mismatched panels will perform well but will not be optimum. The panel amps will get reduced to the lowest common denominator as will Vmp from the individual panels. The IR curve (knee) is different for different amps for a single panel plus there is a mixture of panels with different curves, different technology or manufacturing parameters, etc. The MPPT controller chooses the best output based on what it sees and is unaware of multiple panels with their individual nuances.
But the OPs panels are close enough to give good results.
BTW It's common for DIY solar systems to evolve over time when more power is desired or the the falling price point.
