Torch diagnosis?

[Bradley2448]

Hello everyone on R2R! I have a 90g mixed reef that is coming up on 1 year old in September. Currently contains: Torch
dark green carpet
green LT anemone
Red goniopora
Large no name softie
Sailfin tang
3 klarkii
1 hawk fish
3 bangai cardinals
I am currently running a filter sock into chemipure blue and elite along with a large amount of ceramic and lava rock into a fuge. Lighting is CFLs that were replaced 2 months ago. The torch has been in the tank for 6 months at this point. It took on this pale white shade to its tentacles about a month ago while its polyp extension is still strong. All other corals are responding to regular feeding and have great polyp extension as well. My best guess as a beginner reefer would be that my lighting is sub par. If anyone has any feedback or needs more info please let me know what you think.

Based on what I've read, it seems that it may have lost it's zooxanthellae due to low light.
Not an expert, just going by what I've read/researched.
