Depends. What do you use as fertilizer? How much? How often? Water changes? GH? Kh? Co2?

He meant ferts concentrations. We need at least the product, dose and tank size.

Overall, many plants from the Lythraceae family stunt under many reasons. This include rotalas, ammanias and others.

Too much/little ferts, too little light or co2, too much biomass (plant competition), unfavourable water hardness/pH. It depends.

What do you grow well? Under which circumstances? GH, KH, pH, your city water report, this is basic when growing medium-difficult plants. Thats the price for fixing your plant
