Is the rot or brown spot always on the bottom of the tomato?Or random location?
Blossom end rot is always the bottom of the fruit. The fruit will look great until you flip it over and then YUCK. Blossom end rot is a calcium deficiency. Sometimes there is enough calcium in the soil, but an imbalance of micro-nutrients or SPASTIC access to water makes the calcium inaccessible to the plant. You can spray the plant as suggested. Or, if soil in your area is void of calcium, as you plant the tomatoes, stir a handful of land plaster or agricultural gypsum into each hole. I mulch tomatoes heavily as this keeps the moisture at a somewhat constant level thus not vulnerable to blossom end rot.

More irish potato notes:
When your potato plants start blooming, they are making little potatoes. If you gently dig, you can harvest new potatoes at this time without damage to the plants (take a few from each plant to build a pot of potatoes). Once the plants expire (approximately June in warmer climates), dig. I always spread them out in a barn loft so that they were in the dark and the mud stuck to them would dry completely. As I used them for cooking, I use smaller first and save the largest for last. Large potatoes keep in the natural longer than small potatoes.

agricultural gypsum

At my house that's called 'old drywall, crushed'.

I think a random location, but I don’t remember for sure. What do you mean by SPASTIC?
