sounds like a need some good water. i need a little more info. are you using any nutes, how old are they, what derection are they curling, and any color changes?
there at about 75-80 degrees at all times, they are curling down and in toward the stalks and there are no real color changes they are about a month old, but really small
why don't you read up on nutes in the Growfaqs, that might help. You should look into getting some nutes and put the plant on a schedule. It requires more effort than using that fert. stick, but once you get a system down it's much easier and you tend to understand the plants needs a little better while doing the research. Not only that it probably will get you a healthier plant in the end.
