Im in the process of growing a Northern Lights Auto. It's been going well for the most part so far, except it hasn't flowered yet. It's about 7 and a half weeks old. Today I opened the door and it seems like he new growth is curling. It didn't look like this before (not as bad anyway) and now it's all curling and twisting and just looks a bit strange. I also noticed a couple of yellowing leaves at the bottom of the plant. I will post a lot of pictures. Right now I have the plant under 4 45W CFLs at 6500K. The temperature is about 70 degrees and the humidity about 40. The pH is at 6.7/7. What do you all think?
Is my plant dying?

The pH is too high growgirl. She isn't dying but she is in the early stages of struggling. You also have a spot of nute burn. I would suggest using a water/feed mixture of 5.8 - 6.0 pH to get the soil pH back down to slightly acidic. That twisting and interveinal chlorosis is a sure sign of nutrient problems caused by high pH.
Looks very similar to my problem.

After calibrating my pH pen, and all the pH up/down stuff, my runoff was like the low 5's, so I'm thinking mine was a pH issue as A4 suggested.
