Who Gives A Fish Forums

I've got a bit of a concern with my hygrophila corymbosa - the leaves are turning discolored. Anyone know what might be causing this issue?

I'm no plant expert, but I've had similar issues and it usually points to a nutrient deficiency. What kind of fertilizer are you using - is it a balanced one or something specific for aquatic plants?

I'm thinking it might be a deficiency in magnesium or calcium - possibly. @shakinStevens is our go-to plant expert, maybe he can offer some insight.
