Tips of my leaves are curling upwards *pics*

This is my first time growing and everything was going good 2 weeks flowering -until I noticed that the tip of the leaves is curling upwards .
I tried looking for any past post on this but didnt find any .
I also have the pics of my leaf problem in my gallery ...please check em out and PLEASE let me know what I can do.

By the way Im using the aerogarden on this thing with the overhead lamp above it 3 inches .

i mite be wrong but im positive that ur lamp is too close 3 inches is way to close it susposed to be about 1 1/2 feet away so u dont burn ur plant

Looks like heat stress. What type of lamp are you using. If it's HID then move it to about a foot or two back. If it's CFLs move it a couple of inches back until you see the problem stop.

Alright , I went on ahead and raised it a foot and will be watching closely .
Thanks fellas .
