What causes calcium deficiency in tomatoes?

Calcium deficiency and, subsequently, blossom end rot, is caused by any disruption of water-uptake. Lack of water, even short-term, especially after heavy rainfall, will result in reduced calcium intake. High humidity, which causes a reduction in evapotranspiration and water uptake in plants, will have the same effect.
