sps burn?

[tang daddy]

Hey guys just have some questions and would be greatfull to get opinions on sps, I started collecting a few frags a while back and upgraded the lights on my tank from 175w to 400w. As I learned quickly that 10000k scorches stuff in no time I rushed out to JL's to pick up a more blue bulb. Threw my stupidity I bleached a few candycane melted half my mushroom collection and various other mishaps but lets not get into that and concetrate more on what's at steak. 14000k bulb a few rearrangements and things are starting to colour up so I P/U a green bottle top acro and started it off about midway down which is what I do everytime with frags sometimes on the sand, then moved up to the top about 4in from the top surface and 2 more to the 400w MH is after a week that I noticed it getting faded light colour on the part that was facing the MH the underside normal still so is the coral getting bleached or actually growing?
