green mushroom help?

[chetrod]

I purchased the mushroom about three to four months ago. It was doing well and now it doesn't want to open up as much anymore. I have 3 175 w halides and 72" VHO actinic lighting. I moved the shroom to a low flow low light area and still no change it has been there for like a week alreay. Paramaters are good aside from phosphate and magnesium i don't have the test kit for that.

This is what it looked like when I bought it.

This is what it looks like today

Damn i never knew there were so many problems with yumas. I only have 4 54 watt T5's in a 140 gallon tank but I am keeping a few nice purple and bright orange ones (nothing too crazy) and I keep them relatively high in my tank and they still look great. Then again I cant keep any SPS in my tank it all turns to this nasty brownish color almost immediately after I purchase a piece, even at the top.
