Spotted Leaves

That looks like they got a bit burned from the heat. It doesn't look like a deficiency or nute burn to me. I do think you went overboard with the watering to try and compensate the heat and they are now showing signs of the soil being too saturated. When plants droop in the heat, it doesn't always mean they are dry, it just means the plant is losing water from the leaves faster than the roots can push more up. It does look similar to being thirsty, but you just need lower temps so it loses less water and the roots can keep up with it. The burnt leaves will not recover, but leave them on unless they get really dry and crispy. Take it easy on the watering until they perk up and then you can go back to normal.
