Eggplants not setting fruit what gives

I planted a six-pack of Japanese eggplant seedlings on March 17. The
plants are very healthy-looking and have had many blossoms, but I see
no fruit setting. Am I giving too much water, too much fertilizer?
I water every day and fertilize once a week. Last year, we were
loaded with eggplant in the same vegetable boxes. We have had some
intense heat in the nineties and above recently. Thanks for your
feedback.

It is not your watering or feeding. You would not have healthy plants if either of those were the problem.

Intense heat will certainly affect fruit-set. In addition - the difference between day-time and night-time temperatures can have an impact. Plants like to cool off at night.

To mitigate the extreme heat you can try putting a narrow frame above your plants and placing a 25% shade cloth on it (just stretching it over T-Frames will work) - just to take the worst heat off during the mid-day hours. Another cooling device is to mist your plants during the day, but that can lead to fungus disease, so I can't recommend it.
