What are the key points of fertilizing techniques for hydroponic flowers?

Because they are not grown in soil, fertilization must use a special nutrient solution so that the plants can fully absorb nutrients. This kind of nutrient solution basically requires professional knowledge to prepare, and generally is not suitable for making yourself. The nutrient solution needed by soilless culture plants is made according to the proportion, concentration and acidity of the nutrients required by the flowers. In addition to the macroelements needed by plants, it also contains many trace elements. When using the nutrient solution, you should strictly follow the requirements on the instructions and control the fertilization concentration. Do not apply it blindly, so as to avoid fertilizer damage. The purchased nutrient solution should be placed in a dark place at low temperature, and never stored in metal containers. Different flowers also have different requirements for fertilizer nutrient elements. Generally, foliage plants should be mainly given nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers; flowering plants, especially during their flower bud differentiation and flower bud development stages, should be mainly given phosphorus and potassium fertilizers, supplemented by nitrogen fertilizer.
