Should I use a general purpose or single nutrient fertilizer?

General purpose fertilizers supply plant nutrients i.e. nitrogen, phosphorus and potassium in the largest amounts and may contain other essential minerals such as iron or calcium. These types of fertilizers were developed for ease of use. However, single nutrient fertilizers are widely available and are equally easy to use.
