in the plant developing leaves as you are in it flowers and fruit, so you'd use a formulation lower in nitrogen and higher in phosphorous, such as Miracle-Gro's Plant Food at 15-30-15. Bone meal is an organic source of phosphorous.

Other nutrients that plants need, but in lesser amounts, are referred to as micronutrients and include: calcium, magnesium, sulfur, boron, chlorine, copper, iron, molybdenum, and zinc. These are usually available in the soil in sufficient amounts.
