My girfriend swears by epsoms salt to grow her peppers nice and big. This year I am going to try it.
I would say start with a small amount like a teaspoon spread around the perimeter of the plant but not on it or too close to it.
Good Luck and hope you have a great pepper crop this year.
One year I planted sweet corn in a square and planted the bell peppers inside the square and watered and watered. The peppers seemed to like the water and the shade. I would recommend a mulch to hold the moisture, but the peppers do like the water and the heat and the light shade.
