Forest Fire digitata and setosa

[blacknife]

my forest fire did about the same thing, I had it mid level pretty much under a 250w radium and it was mostly white with the green parts turned a light lime/florescent green, I notcied ALL of my sps were pretty pale and slow growing so i removed my gfo and have been making little changes to try to bring nutrients up, the main piece is still mostly white(but growing fast) but an encrusted frag plug that I have kept in lower light areas has regained some green. just last week i bumped the main peice out of its place while trying to pull some of the lasts tufts of ha am fighting and moved it down to a lower piece of real estate. If its growing fast take a couple frags, try one higher and one lower light and see what happens. Either way in a couple months you will have a couple frags to trade.

I was having a similar problem with many of my sps colonies, mostly green and purple, they were washed out and some had almost bleached tips as well. Turns out my nitrate was too low, I started dosing calcium nitrate and it has made a world of difference. May not be the same problem you are having but worth looking into
