I have a sword plant (sold as a broad sword, but am a little sceptical.... it is a sword tho). The leaves are a nice colour green but they have small black spots on them, and one of the leaves have a large black area at its perimeter.
As im new to the planted tank game i am wondering if the plants are diseased, or if that sort of thing just happens. The tank is arelatively low light tank (about 1.75W/Gallon). Also in the tank is micro sword, and Eoladia (both doing excellently)
