Nutritional deficiencies and excesses of plants, how to recognize them, consequences and remedies.

What are plant nutritional deficiencies?

When we talk about nutritional deficiency we are referring to the lack or defect of one of the elements of plant nutrition. This type of problem produces a series of obvious effects or symptoms that slow down the development of the plant and if neglected can cause serious damage up to and including the death of the plant itself.

Nutritional deficiencies can of course occur in all types of cultivation and species, both when working indoors and outdoors. Symptoms are generally evident in the leaves, both above and below, as well as in the rest of the plant, from flower to stem or in development. Unfortunately, the symptoms are not always clear and identify a single deficiency, which is why it is always good practice to try to administer correct doses of balanced and dedicated fertilizers as well as sticking to the fertilization plans of the chosen product line to avoid incurring these annoying events. If a nutritional deficiency is suspected, products containing microelements are used, while single-component products are recommended when the deficiency is precise and identified.

Deficiencies can also be caused by parasitic organisms and it is always important to ensure that your cultivation is free of them in order to avoid treatments that would be useless and sometimes aggravating.
