A lot depends on the age and density of the sphagnum and the type of pot it's in. If your Phal is a typical box store type, then the sphag is probably old and compacted (=water less often) but in a tiny pot (=water more often). Anyhow, to keep it going until you can safely repot it, I'd check that the top layer of sphagnum is dry to the touch and maybe wait another day (or two) to water. (If the leaves start to show veins AND you can see living roots, then it needs to be watered more often.) Also, Phal roots are apple green when they are full of water and silvery-green when they're dry - if that helps your decision.
Of all the things I learned in grade school, trying to avoid cooties was the last one I expected to use later in life.
