Could this be from a combination of...

Overfertilizing (liquid miracle grow bottle says once every 2 weeks, I use 1/4 dose every 2-3 DAYS)
Overwatering (some posts say to wait until the top 2-3 of soil inches are dry.. I always water when the top 1/2 inch is dry)

It appears everything on the BOTTOM is dying, and working its way up. I don't know what they mean when they say "nute lock", but maybe the bottom leaves are absorbing too much nutrients and dying? And the top are doing fine because they're farther away?

All photos were taken at the same time.. some just look different cause of Photoshop/lighting. First time grow. I have 4 lamps. 2 overhead, and 1 on each side of the plant. These are kept on 24/7. Two overhead lamps are 1 6500k Daylight CFL each. Two side lamps are 1 6500K Daylight CFL AND 1 2700K Soft White each (y-splitter). I'm using Miracle Grow Liquid All Purpose Plant Food at 1/4 strength. I water when the top soil is dry or just Rating: 5
