If pots.. are they black by chance? If yes, never use black again, Also wrap those black in cloth thats not black.. reflect the light instead of absorb it.
If in ground.. Shade them.. Get Shade trees.. Get a shade tent setup.. something to shade them during the hottest part of the day.
WATER THEM! If there that hot and droopy there likely thirsty as fuck too! Cool water goes a long way. Don;'t wait till noon tho, early morn or late at night, and a good foliar spray when lights go down help cool then off too.
Outside that picking a better place to plant them next year.
Move the pots to shade, If there still droopy lift the pot is it light of heavy? if its heavy over watering back off.. if its light you needa up pot them there root bound in those pots and the water is runnign right thru they can't get enough.
Outdoor is a bitch..why i said fuck it less then 2 weeks in and switched to indoor lol
