The smaller leaf is off a Purple Bio Diesel, still in veg in 10 gal coco pots. Started happening when i switched it from HPS to MH, not sure if that had anything to do with it. Almost a waxy look with rough edges.

The second bigger leaf is off a Candy Kush also in 10 gal coco. Started happening within 24 hours. slowly starting to curl edges on bigger fan leaves.

Light is too close. Its heat stress

I had some leave twisting at the beginning of my current grow. I believe mine was caused by underwatering and/or unecessary addition of CaMg+.

But then..,I am not seeing the waxy/rough edges in the pic...that description matches @Diabolical666 's analysis.

Perhaps too much N. Dark color, waxy leaves, edges of the leaves are sharp.

I agree with Hubey, it looks like they might be getting too much nitrogen. Flush with 5.8 water and resume feeding with slightly less nutrients.

That's what mine look and feel like when they are thirsty, and then I water and they're back to normal. Sandpapery feel. Only a guess though. Post a picture of the plant for better help.
