I understand that this can be caused by lack of calcium, I feed the plants twice a week with tomatoe fertiliser they are in a greenhouse with lots of ventilation. I live in spain/

It has been suggested i use bonemeal.

Any ideas please.

Thanks

Blossom end rot is caused by irregular watering leading to an imbalance of calcium. The soil should be kept consistently moist. Use your ordinary tomato fertiliser following the manufacturer's advice.
