Leaves curling, a little dry/burned

I have a clone that has taken root (quite well, actually). A couple days ago, I left it alone for 8 hours, perhaps too close to my halogen bulb. I have three fluorescent bulbs and a halogen (mainly for heat because it's cold where I'm growing). Anyway, I noticed that the leaves on the top of the plant were curling together like being folded in half. One of them was burned on the edges.

I have since raised the halogen bulb and re-potted it into a larger plastic tub with fresh potting soil. I have been misting it several times a day both before and after I noticed this issue. I'm pretty sure it's not normal for the leaves to fold inward, and I know the burning is not normal. I clipped one of the leaves that looked dead and took pictures for diagnosis.

Please help! My clone will thank you! Pictures of problems:


I do have new growth that looks healthy coming up from the parts below, but I am not yet sure if the growth has been stunted. I really want to keep this plant healthy, so I'm looking for an early diagnosis. I'm fairly certain it was just too close to the halogen bulb and got a bit dry, but since I'm not sure and don't want it to spiral downhill, I'm looking to you guys.

Either the light is too close and your getting ozone burn or you need to just water that bad boy and back off the nutes..If you dont see and change consult expert..imo

No nutes, just cold. The area I was growing in wasn't heated. Moved it to my storage room and sat it on top of my web server. It's now nice and toasty, and it is continuing to grow. I clipped the dried and dead parts, and it's really starting to grow fast now.

Make sure you check your temperature between your lights and the top of the plants... Those leaves curling up could be an indicator of heat stress... If they start twisting anymore than they allready have... you know your problem...

Although, you could have a seperate problem... possibly nute burn... flush them your next two waterings and see if they recover... BTW, What's your pH?

I wouldn't advise keeping the "bad looking" leaf trimming to a minimum... The plant will shed those leaves when they die completely... just let them do their thing... Sure, it's not the greatest thing to look at (some ugly leaves on your baby), but it's not hurting it any extra...

Keep us updated and good luck!!!

She's doing much, much, much better now.
