About 2 months ago I started a small nano tank. After it was cycled I planted the rotala rotundifolia from tropica 1-2-grow , and at first it was growing really fast. I was dosing tropica specialised and premium ferts 0.6ml 2 times a week with 40% light brightness. I than added co2 and increase the light to 75% and started dosing 3 times a week and it really started to grow, also increased some iron dosing. Than it stopped. I increased a little bit of co2 since I thought it was stunted. CO2 drop checker is dark green to green all day. I also increased the dosing of the micro nutrients, but nothing changed. This sunday after the water changed I started dosing the JBL NPK as I am suspecting it's a macro nutrient defiency or a micronutrients toxicity, since both the specialised and premium ferts of tropica have micro nutrients. Light is also at 100% now. As regard to water parameters I am using RO water + dennerle shrimpking salt mineral gh/kh. Ph 7.5 without co2 and 6.5-6.8 with co2, GH 10-12, KH 3-4 and temperature right now it's varying from 77-82F. What do you think it's wrong?

Co2 issue , you increased the light to 100 % but didn't increase the co2 ,
If you have high light and good levels of CO2 rotala will pearl , but i gues you lack CO2

What soil do you have ?

Hi!
Andrei is right! What kind/intensity light you have? How light come over it?
In my aquarium, I had to trim it two times per week. At a certain moment It becomes invasive.
And I used Tropica Universal plus Ferropol plus Khalium-Potasium.
