Some of my tomatoes have a rotting spot at the bottom

Question

I have 5 tomato plants and some of the tomatoes are developing a rotting spot at the bottom. I read this was due to calcium deficiency. Some sights suggested spraying the foliage, adding crumbled egg shells to the soil….. so many choices. Can you please tell me what would be the best thing to do.

Thank you.
