I recently set up a 20 gallon tank, and added some plants. One of them
developed brown spots on the leaves. You can see the photo at


It's planted in the middle of the tank, where there is more light. Could
this plant be getting too much light? The other plants, bought at the same
time, look great.

The disease, whatever it is, seems to be progressing. Is there anything I
could do to save this plant?

The tank has beed running for two weeks. pH is 7.8, ammonia 0, nitrite 0.25,
nitrate 5 ppm. I alwo added some liquid fertilizer.


Another thought. Those swords are often grown emersed and the foliage
doesn't always adapt well to being submerged. If that is the case,
healthy new foliage will begin to grow from the middle of the plant.

I think the brown holes are a red herring and that it's a Nitrogen
deficiency. The new leaves aren't green, and they should be.
