I dose alkalinity at night from when the lights start to ramp down to when they start to ramp up in the morning. I also dose a little Alk right in the middle of the light cycle to help with the swing. Make sure you’re using soda ash, not sodium bicarbonate if you’re wanting pH benefits.
Calcium is done during the day. Starts an hour after Alk is done and stops an hour before Alk starts in the evening. Hope that helps

If you mostly want to stabilize alk, dose more during the day. If you want to mostly stabilize pH, dose more at night.
