What are the temps? A 400w should be about a foot from the plants unless it isn't cooled well enough. Even if it is too hot, temperature isn't your only problem. Check the soil Ph. Carefully pull the plant out of the pot and check the roots for binding. This is usually easier when the soil is on the dry side.

^No doubt, 3 feet is too far away. Even if it's not air-cooled, it should be at least within 18". I run mine at about 14", without any problems. :)

Heres the thing, i feel that this is proably a lockout and this problem is going to spread. I would get cal-mag to help with the nutrient uptake.
