	Sounds like the light levels are too low.  Both the Hygrophila and
micro sword appreciate a high light level for proper growth.  The Java 
fern will grow, just slowly.  I think if you double your light levels,
you'll see a significant change (and perhaps algal bloom, in which case
you're going to have to give in and do regular water changes!).  You can
do anything else to the tank, but if you don't have enough light, you'll
never see proper plant growth.
