Failing tomato plants

Question

I have already harvested at.least a half dozen big tomatoes & now they are failing…FAST!!!! I live in missouri & it has been terribly hot here with very little rain. The plants have a lot of tomatoes on them but I’m afraid at the rate that they are failing the tomatoes won’t get ripe before the plants are dead! Any help would be very much appreciated. Thanks

Water, water, water! They are drought tolerant, but once the humidity drops, they will no longer fruit, and look poorly. Also, I would add a little potassium phophate. I am seeing a potassium deficiency starting, and the phosphorous will help with fruiting some.
