Laura, your tomatoes have to be happy with soil like yours! I've debated about foliar feeding but have never understood how the plant absorbs nutrients through its leaves. Should try it though, my green beans are looking anemic.
Three of my Early Girls have bitten the dust. They were on the outside of the garden so I'm thinking the heat difference made the difference. Our dewpoints are still low so I'm still spraying the plants down and covering them with sheets from mid-day on.
