Same thing happened to my Rotala Colorata. First few days, it was growing great. Red leaves and everything. Then my tank had a bit of green water attack it. That along with some surface film, the light was just being reduced way too much, and the leaves went back to a green color and looked a bit stunted.
I've found that high light + the right amount of co2 really helps.
