what causes bottom end rot on tomatoes?
I have loads of tomatoes but some have BER. Is this a calcium deficiency? How do I treat this?

I also would suggest using Epsom Salt. I use 1/8 cup sprinkled at the base of the plant from the time they go into the garden, once a week.
Just water it in.
I use this on my pepper plants as well.
