PLANT FOOD: Your plants will need supplemental food other than what is in the soil, so buying supplemental nutrients is a very good idea. For the sprouting stage you do not truly need food unless you want to baby your plants. If you do, the sprouting stage requires a NPK'S ratio of approximately 12-8-12. NPK'S stands for Nitrogen, Phosphorus, and Potassium. These are the basic nutrients required by plants, and most plat foods have other added nutrients, that the makers feel improve plant growth. For your growth stage you will need food with a NPK'S ratio of about 15-5-5 and in the flowering stage of 10-30-10.
