Symptoms of nutrient deficiencies in tomatoes

Συμπτώματα Έλλειψης Θρεπτικών Συστατικών σε Ντομάτες

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.
