Crinkling leaves

Its probably not even an issue but I just want to make sure. The top...idk... like 5-10 leaves around the cola are starting to become crinkly and kinda wavey, haha if thats a word. I'll get some pics later cause I don't have a camera right now but thats the best i could describe it. Thanks.

sounds like heat stress-can u back up the lights abit and add a fan to redirect some of the heat

u got any pics for us ??
