New lights cause RTN?

New lights cause RTN?

I just upgraded my other 175w MH from a 12k Reeflux to a 15k Iwasaki...
I noticed my stylo lost tissue on one of its branches (not the whole branch but 50% of it)
the white skeleton is exposed but the res of it looks great and other SPS are looking ok. I moved it down to a little lower spot because since i did not acclimate the new light to the tank. Any other possible causes?

I will keep a close eye on it.

PS parameters are all ok.

on iwasaki you need to slowly acclimate the corals to the new light. that bulb puts out alot of par (more than most 250 watt bulbs)
