Also, I'd switch your Alk supplement to sodium bicarbonate right away and see if that makes the difference for you. I suspect it will.

Did you actually measure the new SW batch before adding?

Again as others said, dosing is to maintain what your tank consumes. After a WC supplement back up to your target levels and once you have matched your dosing to coral uptake, leave the dose settings alone.
