Nitrogen And Potassium For Rotala

[radioman]

My rotala is turning yellow and some older leaves are turning brown. I am now dosing nitrogen and potassium. Should this help?

Are you dosing traces? It could be an iron deficiency. What kind of rotala is it?

 

[radioman]

I am dosing excel, flourish, potassium, nitrogen, and it is a rotala rotofundia or something something.
