the only times ive had this happen is when i bring indoors plants outside, the plants take some time getting used to the new environment and sometimes it might be more light then they are used to and the leaves can lose their colors.
indoors you are growing in a enclosed area (a room or a tent) and without proper ventilation and air circulation heat and stale air becomes an issue. outdoors you have wind and fresh air all the time to draw away heat even if the temps go up to 90-100 degrees. im around the same area as you and im dealing with the exact temps you are describing and my plants are thriving. indoors you are growing in a controlled environment where the grower has to do all the controlling, if you let one thing go the whole system can go out of whack. outdoors you have a self regulating system where you let mother earth take care of the environment. all you really have to worry about is keeping them hydrated.
also, i had to water once a day sometimes twice a day during the hottest parts of summer and had no issues with mold. the plants were drying out too fast for mold to form.
