Rachel,
I am inclined to still think it is the ferts/ CO2. Here is why. I use a
modified Tom Barr method. That means I add ferts according to his
recommendations and do water changes when I can. ;-> WC's probably get done
every two weeks on my high light tanks, sometimes less often, and since I am
one of those folks who "over do" things, my tanks are probably pretty rich.
Our light values are very close and upon looking , the indica is bright pink
in the open "sun" but green in a shaded area.  Might be interesting to see
what happens if you push the macro's up a bit but don't be surprised if the
Alternanthera r develops more brown tones.
This tank houses livebearers so KH is 5-8, GH 10-16, Coral and dolomite
produced but don't know that that should have any influence?
