Contrary to what most folks say, tomatoes like nitrogen. My dad was the best tomato grower that I've ever known and he used 33.5 amonoium nitrate to fertilize them. He's put a ring of nitrogen around each plant when he set them out (said it kept the cut worms from cutting them) then he fertilized them again with nitrogen when they started bearing. I'm a pretty decent tomatoe grower in my own right and I use 2 tablespoons of Miracle Gro. around mine when they've been out for a couple of weeks and do it over again when they start blooming.
Coffee grounds, I dump right next to the plant, when ever I have them.
The secret of growing tomatoes is to keep the water uniform. Watering with a hose just doesn't work right. You over water one day and under water the next time. The tomatoes don't bear right and you generate Blossom End Rot.
Don't know if this is a help or hinderance but good luck growing tomatoes.
