Found out one hour too late that I might have sprayed too much calcium nitrate on my tomatoes. The directions called for 5 lbs of the stuff per 100 gals of water. When I did the math I came up with 8 oz/ gal. After the application I it dawned on me that it might have been too much. I redid the math and came up with .8 oz/ gal. What's this going to do to my tomatoes? Should I rinse it off?

I doubt your tomatoes can absorb that much of it, but yes, I would rinse the plants off now.

It's the high nitrogen that may cause some foliar burn, I think.
