    New leafs by Limnophila rugosa get dark green and very thin and almost transparant. What lack of nutrient?

    Hey Kurt - what is your fert routine? This plant likes generous macros, especially K. I want to say the symptoms are likely low Ca or nitrate.

    I have measured the nitrat to 10-15 ppm. I have not measured the K, but I fert to a level of 8 ppm but I think it is higher because i also ferts to 8 ppm of nitrat (measured to 10-15 ppm)


    I do`nt think it is lack of Ca. My tapwater has a dH of 16-18 and I remove Ca by oxalsyre to a level of 6-8 dH
