Your parameters are fine. High mag is not going to hurt and will come down on its own.
What are the big 3 when you make up new salt? My guess is the salt you use just has high mag.

Lowering the salinity from 35.6 to 35 ppt will drop magnesium from 1514 ppm (assuming that is accurate) to 1488 ppm. Not a big drop, but there's no reason to be above 35 ppt.
