What size tank and how much light do you have over the tank where the plants aren't doing well?

A good fertilizer for low light tanks is Flourish (just the regular kind).

IME Amazon swords are not low light plants....they really grow better with atleast 2 watts per gallon or more lighting (will need more in smaller tanks, but Amazons will outgrow them). You may want to dose some Potassium as well as the regular Flourish, since swords especially can show deficiencies. I'm gonna guess though, that the reason your sword isn't doing well is the lighting.

A nutrient rich substrate also helps, but if you don't have one now, you may not want to switch over to one in an established tank.
