San Marzanos turning brown

Anyone know why the bottoms of all my San Marzano tomatoes are turning brown? So sad.

My wife is the master gardener, so this isn't from me.


Blossom end rot..lack of calcium.

I don't know. But she said there is a spray for that, so maybe they have it.

I read online that you can use tums. Just buried 5 in each plant pot crushed up. Ill look for the spray in the morning. Had to cut 12 tomatoes off. 6 more potential to cut

If you havent
Prune the bottom leaves, get some air flow and stop them touching the ground.
Dont water the leaves or let water splash up on them.
If you smoke dont near the tomatoes or wash your hands.
If there are a few plants that have this and the rest are good remove those plants
It could be a virus
