Million bells are supposed to flower all summer given full sun, water and fertilizer.
Are you keeping them watered in the intense heat? Though they like full sun and warm weather, extreme heat can reduce flowering. Soil should be moist but not wet. Too wet and root rot sets in.
They are heavy feeders and need a complete fertilizer. Though some say too much nitrogen inhibits flowering, calibrachoas need a lot of nitrogen so don't skimp on that in the fertilizer.
