I just bought a granular fertilizer with 14-14-14 label and another fertilizer that needs to be diluted in water with 15-15-30. Which is better?

A really simplified interpretation of NPK. N = nitrogen (for leaves); P = phosphate (for roots); K = potash (for flowers). It depends on your soil. If you have an excess of potash, then 14-14-14 would do. Roses like potash and if your soil has a deficiency of potash, then 15-15-30 would be better.
I almost never use chemical fertiliser for potted roses. Too burny. I use lucerne hay topped with sheep manure, and once every three months perhaps, 1/4 teaspoon of sulphate of potash.
