Echinodorus

[Martsmart]

Hi I have a planted discus tank (see picture) my plant growth is good (very good) except for one plant my Echi. I have a microdosing pump that inject on a daily basis Flourish and Flourish Excel when the light start. No Co2 injection, the system is available but there is no impact when I shut down the system. I recently transfer my echi in a seperate jar with mold and flourish root tabs, I did not resolve 100% but the growth improve significantly but still under my expectation.In the past echi were in good shape but something happen and I can not find the cause.Water change are automatic and about 5-10 % daily during the night. Nitrogen level is ok since heart beef food for discus help, level is near 15-20 ppm. Phosphorus level is near zero in my test, I have doubt about the result of this test .

What I should try next ?

Thanks

Martin

Looks like something is munching on the leaves. What fish are in? Any pleco''s?
