3. very useful thanks!!
4. Epson salt
5. If you are growing tomatoes hydroponically you can add nitrogen by using CaNO3
6. First of all, love the comment "Ben stein" all I can say is "Beuler??". Anyway, second love the comment about rain, I was worried til I saw that. We've been blasted with rain here in the Midwest, so.. Need to miracle gro it I guess. Thnx for advices..
7. How about bat guano, it has a lot of nitrogen, and a minor amount of P and K. I think the same with blood meal as well. Manure is kind of hard and stinky to add to container grown tomatoes. There is a video here that say yellow leaves on cucumbers can be fixed with epsom salt/magnesium, so Im guessing that might help with tomatoes as well.

13. @marshallhenderson81 As he said check the soil, make sure it is not too wet as well, too much water can cause the same problems. But rain can also wash away nutrients.
