This is the 2d year my tomatos have dark spots (big) on the underside.
Someone told me I water too much. Someone else told me I water too little!
I am not convinced it is the watering. Maybe something in the water? We
have a well.

Would appreciate anyone who knows weighing in.

Next year, sprinkle a handful of wood ash per plant a month or two
ahead of time. It will not only prevent BER, it will also improve the
flavor of the tomatoes (if you have acid soil, which you probably
have).
