How do you know when it is time to start dosing?

I am new to reef tanks. My tank has been cycled and stocked since march. I know everyone says keep parameters stable and big swings are not good, but what exactly is concidered a "big" swing? I am using red sea coral pro salt and finding that my alk is dropping rapidly while my ca seems to be staying fairly consistent.

For example. Doing weekly water changes of 20%, my ca is staying between 420-440, while my dkh is reading 9.5 down to 6.5 before my next waterchange. I feel like i should be dosing alk.

Mg is almost always exactly the same reading every test@1420.

Tank is 50/50 mix of sps frags and lps.

Sg 1.026
Nitrates 0
Dont have a phosphate test kit yet.

I am using red sea test kits.
