PH is low?

For that mater neither is 500 cal, the high 13dkh might be some of the extra mag in that reading, it's nice to use the kalk, there's lots of side benefits..

1580 ppm is high for magnesium, but magnesium doesn't affect the pH. Lots of people run in that range because a number of salt mixes come with a very high magnesium level. This article might help:

But like I said the probe is reading right because when I put it in the 7 or 10 that's what it reads eventually

Reads eventually meaning it takes it time to get there? Sounds slow , if it's slow it might be bad, ph probe threw a pm2 or direct to apex?

It's connected to the ph hook up on the Apex Base next to ph/orb

So you have a classic, move it over to the other port. Go into classic dash change that port to ph recalibrate and check..

Curious does cool air like 40 degree intake to the skimmer might lower ph by a chance ?

The lower air temperature won't make a noticeable difference. The carbon dioxide content is the key. The temperature of the tank is regulated by the heater, so it's not going to vary appreciably.
