If your plant has good roots that can take hold, the plants will live no matter the heat. You ought to see what a tobacco field use to look like two afternoons after planting - and that was in 90 degree heat and bright sunlight. Only the heart of the plant survived. Ditto for tomatoes.
My problem is trying to micromanage every plant. See a white leaf - grab the Epsom salt solution. Check them every morning, afternoon and night to see how they are doing. Adjust the lights daily, if not more often.
Alas, the affliction is carrying over to other plants - I find myself checking the potatoes a couple times a day and the tomatoes at least once a day.
