What's wrong with my plant!?!?!

I was gone for a day and a half and when I came home some of my plants grew 4 inches, but then I noticed a few had this dry wrinkled tecture on the top leaves. only the top three leaves have it. but the Train Wrecks have it worse than any of them. Here's a pic of the worst one. What is wrong?! The first two pics are the pics of the worst plant (a Train Wreck). the other two are the best plant (it's a White Widow)

Oh, I have 1000 watt air cooled lights , I use Superthrive and Alaskin fish ferts With some blood meal in my soil. My room NEVER gets past 75F. Today when I got home the room was 69F. Last night it might have got real cold with the lights off. Oh and the humitity was at 43. I forgot to mist them in like 4 days.

dude they look fine, i had this happen and next thing i knew my leaves flattened out and expanded in width tremendously!

Are you sure? It does't look right at all to me. I know the white widow (the last two pics) looks good, but the Train Wreck (the first two pics) Look really wrinkled and messed up. Did you inlarge the pic and see the wrinkles and shit? I'm the Newbe, this is my first grow, but I was just positive something was wrong.

dude...not a big time pro gardener here...but your plants look fine to me...could it be the misting thing u were talking bout ???

Maybe they are just growing faster. Like mentioned before they will probably flatten out. They look like pretty new leaves.

I hope you guys are right, I really want to try this Train Wreck and I'm taking this grow kind of personal, they're my babies. My Grapefruit Sour Diesal Kuch is showing nute burn, what do you think?
