Count them, 15 flower buds formed on day 15 after three tiers of true leaves had developed. The foundational leaves provided the energy to build this new structure, and the DNA identifies when and how it is made. Each bud has the potential of forming a flower, each flower a seed pod, and each seed pod a dozen seeds. The color of the flower is already starting to show, yellow. This is a large change in the plants grow, the flower is more complex than the leaf and the flower purpose is for replicating it DNA. The plant is designed to multiply. So, not only is the plant programmed to replace itself, but also to make a lot of copies of itself. It looks like the plant is getting enough light, water, and nutrients.
