Nutritional Deficiencies of Tomato — Vikaspedia
The very low mobility of calcium is a major factor determining the expression of calcium deficiency symptoms in plants. Classic symptoms of calcium deficiency include blossom-end rot of tomato. Symptoms show soft dead necrotic tissue at rapidly growing areas, which is generally related to poor transloion of calcium to the tissue rather than a low external supply of calcium.

Calcium Chloride - an overview | ScienceDirect Topics
As previously indied, calcium salts appear to have a superior activity compared with most other metal salts, but they commonly suffer from a low solubility in water. Calcium formate acts in a manner similar to calcium chloride, but high dosages are required and its solubility is considerably less (approximately 17 g/100 g compared with 75 g/100 g at 20°C).
