The other corals are probably getting blasted with too much light right now as well. They need to be acclimated to a change in light. If you went from a low par light to a high par light fixture, it will be too much for them. If it is dimmable, dial it down a lot to start, then slowly increase it over a month or 2 until you are satisfied with the amount of light. If it is not dimmable, then I would consider using something like eggcrate over the tank to cut down on the light intensity.

chalices adapt to strong lighting (i have over 20 chalice species) pretty good its the change in par that gets them, chalices i have do very well in a 12" tank and 2 x 250w halides , i recently got a bleached chalice that was under a radion and 2 weeks later it was almost full color again under my halides.
target feeding chalices isnt really necessary but like most corals will def benefit from feedings(just about all corals benefit from feeding)
chalices are very touchy with temps as in high temps will wipe them out and bleach them in no time(they like colder waters)
