Hi, Kevin, Hold off on the fertilizer. Nasturiums really don't want much attention. They prefer a light, sandy soil—"poor" soil by some estimates. If you give them rich, fertile soil and fertilizers, you'll get lush leaves at the expense of blooms. Use "good" soil for something that will appreciate it.
Are you watering correctly? Water them deeply until overflowering and then let them get bone dry, and then water deeply again. Usually, watering is once a week.
One of these days (it's still early season in most places), the plants will surprise you with flowers.
