I believe that Ammanaia species, like Nessea species and E. stellata, tend to be "fickle" plants. Meaning that although you may provide the plants what appears to be the optimal growing conditions, the plants may fizzle out or stunt. Some of the best growers I know have constant trouble with the aforementioned plants due to no fault or oversight of their own.
I have seen Nessea and Ammannia sp. grown in horrible conditions. No fertilizers, ok lighting and less than optimal CO2 levels. The plants are small, naturally, but they survive. I have seen Nessea and Ammannia species fail in optimal conditions, great CO2, lighting, and a strict fertlizing regime.
I just don't beleive there is an easy answer as to how to grow those plants. I am not sure it is a case of add this or cut back on that. I am not advocating that you throw up your hands and yank the plants out. I am advocating that you take it easy on yourself and realize that these are tough plants! Patience is the key!
