Your plants look very healthy, and that's a possible explanation.
If they were potted up while they still had plenty of room, and have had plenty of water and food, then the plants will be focusing all their energies on lush green growth and getting bigger. That might explain your plants being slightly later in flowering and fruiting.
Don't go too far the other way, I don't agree with some people thinking they should let the plants wilt and starve to provoke them into last ditch survival attempts to produce fruit and therefore seed. Get the right balance, no need for physiological damage that will harm the plant.
But possibly reduce the watering and stop the feeding until flowers and fruit start forming. One good watering will probably be better than both day and night. Apart from very hot days, it's ok to let the compost partly dry out in between.
