B.Japonica leaves turn yellow

[T S]

Dear experts out there,

Can someone please explain what actually causes the leaves of B.Japonica to turn yellow or what nutrition is the plants lacking?

I dont really know the parameters of my tank's internal but i suppose someone can explain the theory behind those yellow leaves?

Thanks,
T S

Maybe you can let us know what is the amount of light you are using? And is the japonica being shaded. It is a high light plant

I agree with Nicholas, high light is needed for this plant. How big is your tank and how many watts of light are you using? Any C02? Fertiliser (liquid or base)?
