The information on the symptoms of nutrient deficiencies in tomatoes (trophic deficiencies) comes from “The Diagnosis of Mineral Deficiencies in Plants by Visual Symptoms” by Thomas Wallace, M.C., D.Sc., A.I.C., published in 1943.
I found this source from the blog “The Perdic Cafe”, looking for why my tomatoes are opening this year.
I have planted tomatoes in two places. In the first part everything is fine. The plants are green, strong and healthy. In the second part, the plants are weak. The tomatoes crack open (their skins are torn) when they start to ripen.
So I present to you, symptoms of nutrient deficiencies in tomatoes. I hope they will help you. Any comments are welcome.
Tomato – Nitrogen deficiency
Symptoms on the plant.
Weak growth. Thin plant. Grows upwards. Rigid stems and stalks. Leaves are faded green. Occasional purple spots appear. Older leaves turn yellow.
Tomato – Phosphorus deficiency
Symptoms on the plant.
Weak growth. Thin plant. Leaves wilt, twist backwards and develop intense spots of light purple.
Tomato – Calcium deficiency
Symptoms on stems.
The young tips of the plant die. Tomato stems begin to dry out starting from the tips. The leaves die, starting with the new leaves and shoots that are fertile and contain flowers.
Tomato – Calcium deficiency
Symptoms in the Dickey – Zygote
Drying out of the extreme leaves and flowers. The leaves take on reddish-brown hues.
Tomato – Calcium deficiency
Symptoms in the Dickey – Zygma – Zygkton. Dry or black top of fruit (Blossom End Rot).
Drying out of the reticules. Blossom End Rot (Blossom End Rot) appears on the outermost fruits.
Tomato – Magnesium deficiency
Symptoms on the leaves.
Central chlorosis and green bands on the leaf tips.
Tomato – Magnesium deficiency
Symptoms in the dicot.
Central chlorosis and necrosis of leaves. Fruits (tomatoes) show “green backs”.
Tomato – Magnesium deficiency
Symptoms on the plant.
Appearance in greenhouses. Central chlorosis and necrosis of leaves.
Tomato – Potassium deficiency
Symptoms on the leaves.
Slight peripheral and internal chlorosis on new leaves followed by peripheral brown scorching. The ‘scorched’ edges of the leaves turn upwards.
Tomato – Potassium deficiency
Symptoms on the fruit.
Blotchy Ripening on the fruit of tomatoes. Green and yellow areas (mosaic-like) appear on the surface of the red fruit.
Tomato – Tomato Mosaic Disease
Symptoms on the fruit – Tomato Mosaic.
Patchy uneven ripening, similar symptoms to Blotchy Ripening due to potassium deficiency, but the areas of mosaic are more clearly defined.
Tomato – Iron deficiency
Symptoms on the leaves.
Leaf tips are affected. In particular the main areas of the small leaves. Strong chlorotic tinge. The stems near the tips are also yellow.
Tomato – Magnesium deficiency
Symptoms on the leaves.
Chlorotic shades spread over the entire surface of the leaves. Spotted areas become dead.
Tomato – Manganese toxicity (acid soil – complex issue)
Symptoms on the branches.
Stems and stems, especially the joint areas, show necrotic lesions. Leaves wilt and droop.
Tomato – Boron deficiency
Symptoms on the branches.
The stems become stiff. New flowers die and growth is reduced. Side branches grow, preventing the plant from growing taller. The leaves become intensely purple, brown and yellow.
Tomato – Boron deficiency
Symptoms on the fruits.
Tomato fruits are seedless and have a corky texture. The ripening is not uniform.
Tomato – Molybdenum deficiency
Symptoms on the plant.
The leaves are somewhat chlorotic. Intense leaf rotation. Leaves dry out from the edges.
