It may take a few days to present itself, so just keep an eye on it.... longer it takes to display, probably the less severe of a problem... if at all.. if it shows no stress, i wouldn't worry... although if in 3-4 week you see nanners, take note for next grow that it may* have been a bit too much, coincidences aside.
you can ameliorate high temps a bit by increasing humidity too, but consider other factors like mold. maybe not a great idea late in flower, for example.
