Leaves cupping under? What's wrong?

Hi there -

This plant has recently been through a thrip invasion and came out a little scarred but ok, it's growing nicely since last week's trauma. However, I noticed on Friday that this one leaf is cupping under. I thought it was heat, but since then, it's been a steady 75 - 85 degrees in the greenhouse (thank goodness it rained and brought down the heat). This is the only plant that's doing this. My other plants that survived the thrip invasion are fine and are not doing anything odd.

The details:
Plant is in a greenhouse w/ sun for lighting in CST zone.
Plant is in a Earthbox; meaning soil, water, nutes are regulated and do not fluctuate. (The other plants doing well are in pots...I'm not counting the Eathbox neighbor plants since I'm not sure if they are going to recover from the thrip attack completely.)
Plant is in soil (just like the others, but this one is in Earthbox, not a pot).

Photos:

Any suggestions would be GREATLY appreciated (as well as bumps in rep!) - thanks in advance!

& Happy growing!

is that still alive? you need to go buy a book. i suggest a begginers book to touch all the basics on nutrition and lack of. jeorge cervantes has a line a great books and DVD's containing all you will need to know. the best way to become an expert is through alot of reading and even more hands on training...Books are the basics, and even faster than an on-line app. oh yea, also look up Ed Rosenthal, he has some great pointers. remember ones opinion differs from others, so read everthing you can get your grubby little hands on. peace HYER than U!!!!!!!!!!!!!!!!!!!!!
