A couple things. First, you didn’t mention what skimmer you have. You don’t have much of a fish load so if your skimmer is oversized, it might struggle to keep a foam head.

You didn’t mention the age of your tank. You didn’t mention Po4 levels. Your nitrates are really low and if your Po4 levels are low, that would explain the lack of growth in your cheato. Also, most of the corals you mentioned are soft corals which prefer high nutrients and use those nutrients for growth.

Your Alk is kind of high for most of the corals you mentioned, your Ca is low and your pH (assuming 7.4 is correct) is VERY low.
