Answer:
SPROUT
Each seed contains a small parcel of nutrients that is all they need to germinate and begin growing their first pair of leaves.
SEEDLING
As plants' roots develop and spread, a boost of quickly absorbed, well-balanced nutrients fuels the rapid growth from spindly seedling to healthy plant.
VEGETATIVE
Nitrogen is a key component of chlorophyll, the green pigment in plants, so it's the critical nutrient when their energy is focused on growing stalks and foliage.
BUDDING
Phosphorus is in extra high demand at the start of a plant's' reproductive cycle, the transition from growing leaves to forming buds.
FLOWERING
Potassium plays a primary role in producing and transporting the sugars and starches plants use up as they develop healthy flowers and fruit.
