The numbers mean N-P-K (nitrogen, phosphorus, potassium).

In this case you have 0.15% nitrogen (as water soluble organic nitrogen as a
chelated agent), no phosphorus and no potassium. You will also have some
chelated iron, and small amounts of chelated and soluble manganese, chelated
and soluble zinc, and trace amounts of boron, chelated copper and chelated
molybdate.

What roles do the nitrogen, phosphorus, and potassium play?

Plant nutrients. They are required for plant growth. However, excessive
phosphorus will cause an algal bloom in your tank.

Each focuses on a different part of the plant - Roots-shoot-fruits (if I recall
correctly).

Nitrogen (roots) - promotes root growth.
Phosphorus ( shoots) - promotes stem and leaf growth
Potassium (fruits) - drives fruit and flower growth.

Nitrogen is your green leaf/new growth producer, a higher Phosphorous
promotes blooms and fruits, and Potassium does a lot of things being a
general cell builder. That's my backyard gardening version- I wonder if
aquatic plants are the same?
