It's much cheaper to dose what your corals consume, rather than doing bigger water changes.
Your water may be too clean for LPS. That is my problem also. You will need to target feed your LPS if you want them to grow.
Make sure you never let alk drop bellow 6.5dKH. That is when bad things happen to SPS. We keep our system stable @ 7.5dKH.

Well my tank holds 56 corals in 20 gallon water so don't know whether I should say its limited amount of coral
I did have a drop to 5dKh once (possibly for a week even! didn't check) but nothing bad happened (atleast not with SPS). No clue why so (although good for me haha); weird things happen with my tank.
I was planning to do my regular water change this saturday, monitor how things change over the course of next week, and take action accordingly perhaps?
