I just found a single tomato with BER today. I had read previously , here
likely, that it can be due to calcium deficiency. I crushed
calcium/magnesium tablets (for night legs cramps, btw) and mixed with water
and watered the pot grown tomatoes and peppers. Will calcium carbonate from
a pill work for a plant?
We have very hard water here and I was surprised to think that calcium
deficiency would be a problem!
Only one "mater on one plant had it, so far.

Not calcium deficiency but calcium metabolism. The exact combination of factors
that lead to BER is unknown. Uneven moisture, cool spring nights, too rapid
growth--since it will go away all by itself there is no way to determine if any
treatments are effective--calcium is rarely lacking in soils but the plant can
not always make best use of it just why this is so is not clear.
