You just got them(?) so give them some time to grow out. They will all be
quite close in color after some time and when you have all new growth. If
this is not an issue you might try looking at how you plant them or the
gravel might be compacted etc or one spot may have more nutrients etc.
Lower NO3's (less than 5ppm but not absent) will "bring the Red out" so to
speak in many plants but certainly all Rotala's. Even at half the light you
have now. This one tends not to well at high NO3 levels.
