Saving Tomato Plants

Q: My tomato plants are fruiting, but the leaves are turning yellow with brown spots.  Are they ruined?  Can I save them?  The ground is wet/damp but not saturated.  I water them on the days it doesn’t rain.  The other plants in my garden seem to be flourishing.  Please help!  Melissa – Des Moines
A: Fertilize with Miracle-Gro Tomato Food.  Apply Nutri-Cal once a week.  Also apply Fung-onil once a week, but space these two products 48 hours apart.  Use a hose-end sprayer.
