Is Cal Mag good for Blossom End Rot for tomatoes?
If so, how often should I use it and at what stage?
Planted seedlings late and plants are just starting to flower.

In my opinion, yes it is. I use it right when I start fertilizing, and the. About once per week in my rotation. I think a consistent amount of watering is also important to prevent BER. Good pruning practices to promote good airflow is important as well.
