When dealing with fertilizer there are two things that are important: the actual amount (the weight) and the ratio of nutrients. The ratio is the relative amount of each nutrient. In the two examples above, there is an equal amount of each nutrient and so the ratio is 1:1:1 for both of them.
Ratio of fertilizer (N-P-K) The nitrogen contained in this fertilizer is released quickly. The plant absorbs the amount of nitrogen it needs, but the rest is not used. There is a high risk of leaching and burning the roots. VS The plant absorbs small amounts of nitrogen as the fertilizer gradually breaks down.

When rose tissue is analyzed, the fertilizer numbers are in the ratio of 6-1-4 (ref 1). They contain much less phosphorus than nitrogen or potassium. According to Jeff Gillman (ref 3), “there is usually more calcium, magnesium and sulfur in plant tissue than phosphorus”. So why would a fertilizer ratio of 1-5-1...

The powerful fast-acting water-soluble 1.5 lbs fertilizer contains a higher NPK ratio of 12-15-30 blend of macro-nutrients and essential micro-nutrients like magnesium and calcium, which help your plants to fight plant diseases like blossom end rot.
NPK fertilizers. The first number represents the percentage of nitrogen in the product; the second number, P 2 O 5; the third, K 2 O. Fertilizers do not actually contain P 2 O 5 or K 2 O, but the system is a conventional shorthand for the amount of the phosphorus (P) or potassium (K) in a fertilizer.
These three numbers also refer to the ratio of nitrogen, phosphate, and potash in the fertilizer grade. An example would be the fertilizer grade 5 – 10 – 5, which is a 1 – 2 – 1 ratio fertilizer.
