I am watering every 3-4 days . Throughout the summer i increase watering frequency/amount as they grow. My soil mix seems to hold water really wellYou watering once or twice a day in this heat. My plants are drooping around 5pm when I water. As soon as the son sets and plants are out of direct light , they begin to perk back up. They look real healthy, but I think they're getting adjusted to the sudden heat.
