Twisted blades?

[Chronic Chrissy]

OK first off this isn't one of my clones this is my 31 day old northern. Just thought I would clear that up first. Now that you mention heat though it got me thinking. After I transplanted I had to adjust the height of the light and the temp went up to 84(which they aren't used to) for a breif point and it was only after that I noticed the twisting. It is on the top leaf after all(forgot to mention that). I'll go check on them and get back to you guys(very hectic morning). Thanks

Volker, check on those red petioles of yours. The plants look okay but there are a few trouble spots... can't see too well because of the odd lighting, but in the bottom right of the pic there's some fan leaves that may be showing def/burn/lockout... better lit pics on those?
