That is quite a reduction in intensity, which for high light SPS corals could be responsible for less polyp extension. Is it possible to put the old lights back on and see if the polyp extension returns? Your listed parameters look good. The other common cause for lack of polyp extension is usually irritation from a fish or invertebrate like a crab, snail, shrimp, etc.
