Most plant problems are a result of using the wrong amount of fertilizer. Too little and your plants are weak and underfed, too much and you can burn the plant and even kill it. In most cases, it is a judgment call and requires constant monitoring and adjusting as the plant matures. This section contains general guidelines that apply to fertilizing most types of plants.
Hydroponic nutrient solutions are sold in concentrated form and added to your indoor garden's water supply at a certain ratio. The ideal concentration for your hydroponic solution is about 150-600 parts per million (ppm). For most plants, you can narrow that range down to 300-400 ppm. They are typically sold in two or three parts because some of the nutrients cannot be combined directly. Always mix each part of your nutrient solution directly into the water, never into another nutrient type.
