Everything sounds perfect. All you need is a feed that is high in phosphorous to encourage lots of blooms. In case you don't know on every packet/bottle of plant food there is a label stating the N.P.K. ratios.
N = Nitrogen. Nitrogen is the first major element responsible for the vegetative growth of plants above ground. With a good supply, plants grow sturdily and mature rapidly, with rich, dark green foliage.
P = Phosphorus. The second major element in plant nutrition, phosphorus is essential for healthy growth, strong roots, fruit and flower development, and greater resistance to disease.
K = Potassium (Potash). The third major plant nutrient, potassium oxide is essential for the development of strong plants. It helps plants to resist diseases, protects them from the cold and protects during dry weather by preventing excessive water loss.
Organic is best. Avoid Miracle grow.
