Doesn't browning SPS suggest too little light? Try moving them up higher maybe.

+1. I would move them up or increase the intensity a bit on your lights.

What kind of acro? If it's a wild chop might be perfectly normal. Typically browning indicates low light or high nutrients but let's not forget it could just be acclimating as well.
