Nitrogen
"N" of the NPK formula is Nitrogen,
where the percentage will tell you weight that is in the mix.
PlantGlo is a 9-18-9 mix, thereby making the percentage of Nitrogen at
9%.
Nitrogen is used to form basic proteins, chlorophyll, and
enzymes for the plant cells. In short, a plant can't grow without it. Your
plants use the nitrate or nitric form of nitrogen immediately because
they're soluble.
When fertilizing, remember that too
much nitrogen can be as bad as too little. Plants can suffer nitrogen burn
or grow so much foliage that they never flower.
