Curled leaves

I just moved in three plants from outside to inside. They all looked fine, except for now some of the newer leaves are curving, but there are no spots or burns that i can tell of, yet at least.

I'm thinking if anything it might be due to heat. But I have a fan on them and they dont seem to be hot. is there any sure-fire way to know if its the heat?

there are pics of a couple of the leaves. i took the pics as soon as i noticed so not all of the leaves are curling, just a few, im hoping that ill figure out the problem, if there is one, before the rest curl and do the same.

Thanks

Heat could surely be a factor. They don't look too bad. What is the temperature?

The first pic the leaves look to be taco-ing (curling up from the edges), in the second there is one leaf that looks to be clawing down. The taco-ing is a heat stress issue, while the claw is often nutrient burn (too much nitrogen)/pH fluctuation/salt buildup.

well i added more pics and it seems to be gettin worse =/ i moved the lights up higher and took off the shades around the bulb to see if maybe that cools it down a bit...

Ill give it a day or two i guess =/
