Symptoms of Nutrient Deficiency in Plants

A deficiency in hydroponic nutrients will present with very specific symptoms and symptom combinations, with a wide range of severity levels. Plants are more impacted the longer they are left without the nutrients being balanced to needed levels.

Providing your crops with Plant Magic nutrients will guarantee healthy and strong plants, which will maximise yields. It’s vital to keep the following symptoms of nutrient deficiencies in mind to ensure that any unbalance is quickly solved:



With symptoms appearing on the entire plant, a nitrogen deficiency will translate to the plants being light green while old, lower leaves start to yellow and dry to a brown colour. A visible nitrogen deficiency is caused by an excess of chloride.



Should plants appear dark green but with a red or purple tone, with old leaves yellowing and drying to dark green, there is a phosphorus deficiency. Acidic soils can make it more difficult for plants to absorb phosphorus, so it’s vital to measure the pH level before planting.



If symptoms present only on leaves and not throughout the entire plant, older leaves will scorch or wilt the edges becoming necrotic. A noticeable potassium deficiency is caused by an excess of calcium, sodium, nitrogen, and magnesium.

Wilted Flowers



Older leaves becoming yellow at the edges but remaining green in the centre, while the rest of the plant remains unaffected, is a sign of a magnesium deficiency. Calcium or potassium, alone or combined, can cause a magnesium deficiency.



New leaves that are necrotic or distorted with the terminal bud of the plant dying represent a boron deficiency. Calcium causes a boron deficiency when it’s present in excess in the soil.



When a plant’s new leaves are necrotic or distorted with the terminal bud surviving, but the plant is stunted and the leaves distorted with a blue-green tone, there is a copper deficiency. Both molybdenum and phosphorus in excess cause copper deficiencies.



A zinc deficiency translates to interveinal chlorosis of new leaves with rosetted and shortened stems. When phosphorus is present in excess in the environment, it causes a zinc deficiency.

Wilted Sunflower



There is a calcium deficiency if plants’ new growth is necrotic or distorted, with the terminal bud surviving, and new leaves distorted with necrotic edges. Potassium and magnesium cause a deficiency of calcium in plants.



New leaves showing interveinal chlorosis with stems being shortened or rosetted, and leaves not presenting necrotic spots, point towards an iron deficiency. Plants have an iron deficiency when several nutrients are in excess: molybdenum, nitrogen, bicarbonate, manganese, nickel, phosphorus, and zinc.



Unlike with an iron deficiency, leaves present necrotic spots when there is interveinal chlorosis and the stems are shortened or distorted. Phosphorus and iron in excess cause a deficiency of manganese.



If new leaves are chlorotic and it spreads to the entire plants, there is a deficiency in sulphur. Similarly to nitrogen, chloride in excess in the environment causes a sulphur deficiency in plants.

It’s important to monitor plants to ensure there are no nutrient deficiencies. Get in touch with our team today to know more about our products.
