Anubis Is Dying

[tmoney7]

I have some anubis plants in my 10 gal with some cherry shrimp and most of my plants are doing fine but one of them has a leaf that is wilting and turning kind of yellow and another one has black spot all over it as though its just dying.  Anyone know what could be causing this my pH is kept at 6.2 my ammonia is 0 and my nitrate is 0. What am i doing wrong!

YOur nitrate or nitrite is 0? Plants need nitrate in the water. Your could try dosing iron suppliments. I do that and get really good results.

Anubias is grown emersed. I expect this will be an old leaf. Remove the old leaf and you should see some new growth.
