Depending on your lighting and need for extra nutrients, you would be better off dosing a mix of all Macro and Micro nutrients for your plants.
A healthy tank is base on a balance of light, fish, plants and nutrients. In the case of nutrients, this means N,P,K and Traces.
If you have a low/moderate light level an all-purpose fertilizer would be a good option.
