Aaron you are correct. I have always high levels of nitrates because my tap water comes like that ( around 20 ppm) so, to me also, high levels of traces plus intensive light are the key to get this colour from Rotala pink. I recently upgraded my lighting from 4 X 55W PC to 4 X 39W T5HO and boy, the plants took off with beatiful colours, especially the red ones!
