Soil: Lowe's generic top soil

Lights: 4 26w daylight 6500k cfls @ 1600 lumens each and 4 24" 6500k daylight tubes @ 1025 lumens each. 10500 lumens total in a 2x2 space, but only using about a 1x2 part of it so just a lil over 2 square feet used.

It seems like all the leaf tips are browning and like the growth thats been there for a while is pale.
