Am I doing Dosing correctly?

[namlessdude]

Can you help me figure out whether I am dosing right?
I bought the 1+2+3+ aquaforest dosing jugs as my first attempt to dose my tank. I did the test and found that my tank is losing about 0.25dkh a day of alkalinity and about 6ppm calcium per day.
I raised thing to:
420ppm calc
8.1 pH
8.3 dkH

Then, i started dosing 45ml of each of the 3 containers on daily basis. Each element gets split across 3 dosing points in the day with an hour between each of the containers. For example, 1pm is 1+ container, 2pm is 2+, 3pm is 3+, then back to 4pm with 1+...

Is this schedule ok? And am I doing it right?
My parameters have been consistent for the past 3 days but closer to night time (around 3rd dose schedule) my zoas shrivel up. Not sure if they're sleeping or something is off.

I noticed browning on my nephthea corals and here's a pic of my closed zoa.
I turned off my dosing pump to get advice
