...I don't have much experience with high temps like that, but I do have a little. Some thoughts... water more, put some coco coir as mulch on the surface of the soil, use coir in your soil mix to help water permeate the pot and also hold moisture some, mist the plants in early morning and evening, put a wrap on your smart pots that reflects heat – you can use white Tyvek, or reflective bubble sheet, or a cut up white feed bag, etc. ... held on with clothes pins....
...With mulch on the surface, and wrapping in heat-reflective material, you may not need to use shade, unless temps get above say 95. But, observation is the best guide. If you see no wilting or heat stress evidence, you're probably OK.
Here's what I observed when temps got too high in my greenhouse. I call this alligator leaf. Some phenotypes were more susceptible to this.
