What type of light are you using and how close it it to your canopy. May want to raise your light..
Does this look odd?

i love my plants to sweat especially under 24hr lights, however u do not want to cause heat stress and the way u can tell this is if your edges are curling like in ur pic... or they are canoeing (folding in half length wise)like in your pic....defined veigns/leaf structure ...like in your pic , or extreme dryness (this means u sweated out all over ur stored moisture) this happens more in 24hr lighting because theres no lights off period for it to re-stock or cool down ur plant is constantly working ...i like 24hr light thats what i use i get awesom e growth rate healthy plants and imo its faster.... but u got to keep an eye on them ...if your using cfls just back them up a few inches .... if your using mh on just a couple plants then ur a weirdo , as cfls are great for vegging just expensive and hard to find in 6500kThats heat, the plant needs to transpire thus its having a hard time due to heat, ventilation and low moisture, im not sure if you have ever seen water on some leafs when ur lights turn back on but if u do theres a sure sighn that its heat.
Using LED (Area 51, sgs-160) in veg mode. It's about 20" from top of plant.

Check for pythium in the roots. This type of curl is one of my first symptoms for it.

If it was pythium, his plant would be stunted and the leaves would yellow and die.

not necessarily as I stated, that plant looks exactly like what I consider early signs of pythium in my system. Its worth a check on the roots at any rate. White and fuzzy, no pythium, brown and stringy, you've got pythium.
Can they be white and fuzzy in soil?

Yes, its easy to see a brown root and think its just dirt but its pythium. Look at some google pictures of healthy roots and it will be obvious in a side by side. Its not just color you are looking for, healthy roots are very fuzzy, unhealthy ones are stringy. Also healthy roots smell like fresh cut cucumbers.
