I meshed my impeller blade with turbogrid, which gives overall good y+ numbers, however on the traling edge the y+ values are high, because here is no option to add a first cell size there.

Do a sensitivity analysis and work it out. Make a few meshes with different y+ values and different sizes of the large y+ region and see if it makes any difference.
