Sounds like a great tip, Terri.
And yes, Epsom salts is good on tomatoes as well as lots of other plants. Some people just sprinkle it around the plant but I like to dissolve it and water it in so I know how much the plant is getting. A tablespoon per gallon works well for one tomato plant, and also for my orchids where I spray it on. It's highly soluble so it is either used by the plant right away or disappears quickly if you're irrigating a lot or it rains.
