Looks like the coralline is bleaching. Lots of factors can cause this, from salinity issues to calcium levels. What are your water parameters?
Also, I'm guessing from your join date that your tank is very new, is that a good assumption?
Livestock? Clean up crew?
What is you salinity and magnesium at, are you sure about the calcium being 0? you should be around the following, Salinity 1.024-6; alkalinity 8.3-9.3 on KH scale; calcium 420; magnesium 1300
I'm not really sure what you mean by "white creamy stuff," but if your not talking about the rocks themselves then what your seeing might be sponges of some sort or perhaps a fungus or bacteria.
How does it feel to the touch? Does it come off with a brush? For a tank that's not even a month old things like this would be pretty common. The link below might help.

I thought Mandarins could only survive in established tanks with a robust pod population... What is it eating?Hello, yes Im totally new, launched the tank 23rd January.
I bought the liverocks online and I got after two days shipping some full of the white creamy stuff, some with mix purple coraline and white creamy stuff and some with green coraline and white creamy stuff.
My levels are as below (tested just now) :
Ammonia : 0
Nitrites : 0
Nitrates : 0 it was under 10 past few days and just now I tested it show 0, maybe because I added prodibio biokit reef today...
PH : 8.02
Temperature : 26 degrees Celcius
Phosphate : 0
Calcium : 0
KH : 7
One clownfish, one blue/yellow damsel, one mandarin, two hermit crabs, and 4 snails.
