leaf curling

my humidity is high, around 70%, temp is 80-83 during the day and 70 at night. i just transplanted 6 girls and two days later 3 have curling on the leaves, not the newer ones just older ones. there not drying out or yellowing so i hope it's just stress. any advise is appreciated. the other ones look great and the rest of the plants in the tent are also just fine.

How's your airflow, are they getting enough fresh air? It could just be the heat relative to the other environmental conditions. While low humidity will cause leaves to do that there are a couple things that cause the stomata to restrict reducing transpiration.

i am supplementing co2 and the tents co2 ppm is 1300

The aperture of your stomata are definitely causing your leaves to curl but they look healthy. Here is a little quote of how stomata can act independently in the same environment. Have you cleaned the underside of your leaves the stomata might just be clogged.

"Changes in the degree of stomatal opening reflect the cumulative effect of many physiological
responses by a leaf to its environment. Measurements of the degree of stomatal opening on a leaf
surface provide a convenient visual indication of stomatal response to environmental conditions.
The dimensions of stomatal pores have a big effect on the rate of gas exchange. The rate of gas
exchange for the entire leaf is determined by the responses of all the stomatal pores on a leaf to
ambient environmental conditions.
Many researchers have noticed that stomatal response to seemingly identical treatments can
vary considerably. Stomata, then, seem to function as separate entities which respond individually
to the same environmental stimuli. The ecological implications of this “patchy stomatal response”
are the focus of a great deal of current research. Knowledge of stomatal response increases our
understanding of carbon dioxide assimilation and transpiration rates, as well as the nature of
ecophysiological adaptations of plants to their environments."

i'll give it a try tomorrow, thanks.

i'm not sure that thats the problem, i went over and washed the bottoms right before the lights went out. today they were a lil worse, i made it there to check after the lights were on about 4 hours. i'm wondering if some sort of mold or fungus may be causing it? there are no bugs. sorry no pictures, i'll have em tonight.
there not being stunted by this either.
thanks

ok so the problem was just stress from transplanting and getting my room dialed in, they all pulled through, although the one i flushed is doing the best.
