When we purchase orchid fertilizer its your basic macro fertilizer. Macro fertilizer is nitrogen, phosphorus and potassium basic nutrients and is benefical for a garden and when mixed with Micro nutrients consist of boron, iron, copper and manganese to name a few, with this balance your garden will look healthier. I have used this technique back in the day when I use to harvest my own vegetables.
Macro plus micro nutrients will be more productive in growth, well balanced, no different than us as beings having a balanced meal.
