I have no idea where is Dan, but I was curious as well. Did they grow any? I can't tell without the "before" pictures... If they don't grow well, I'm curious if you'd try to feed them something.
One of the staghorns encrusted really fast, and the Porites astreoides started to encrust a little too. The other two types in there are slow growing boulder type coral frags, which I really wouldn't expect to see much growth from in two weeks. I think the limiting factor was alkalinity. My homemade kalk dripper clogged and failed to dispense while I was away. But that's just pure speculation on my part.
