no it will do fine, the big amazon swords (echinodorus bleheri) do well in any light and are therefore the perfect plant for discus tank. Make sure to use a big planter because if you stunt the root growth, you will stunt the plant size as well. I plant mine in small glass shot glasses sometimes just for this exact reason, to keep them small.

to the op your sword will do find under that PAR, from my experience, swords do fine under any light, just get really big and bushy under high light. GitMoe's sword looks really really good

This is plenty of light for a sword, you should get more than one and do a clumping of them in the back right corner. great looking discus, where did you get them??

I thought they might be Kenny discus, I recognize that spotted one. no you will not need to move your light.
