Your so called numbers is the guaranteed analysis. N-P-K as
posted above stands for Nitrogen, Phosphorus and Potassium.

Nitrogen promotes growth of leaves branches and stems

Phosphorus promotes root and flower growth

Potassium helps with all stages of growth and builds
up the plants natural defenses against disease and pests

This is why differnt levels are needed for each stage of growth.

Hope that helps
