Well... I did it, now what?

I thought I had acclimated my new T5 (2 48" ATI's) lights long enough but apparently not. 80% of my original corals are fine and doing better than ever now especially my two sticks. 20% are struggling in a variety of ways (mostly some new frags I had about a 2-3 weeks before I started acclimating the new lights. To be clear, these were "additions to" not replacements. Some are still retracted back, others discolored. What can I do to help them recover?

First, the ugly's

Then you can see other corals are just fine

IMO, spot feed and shorten the photoperiod. Give em a lil more time to get used to it. Did you notice a nutrient drop at all?

Only thing I noticed was MG dropped from 1220 down to 1170. I used some epson salt and brought it back up to 1200. Thanks for the tip on shortening the period. I have noticed was the day goes on, they seem to get more and more unhappy. I did notice recent spot feeding seems to make them puff up a little more so I'll continue with that.

I think the slight mag drop is probably unrelated. seems to be in the realm of test error as well..
One of my favorite threads on nutrients and light.
