Critical Jack Herer- (Day 37/Flower) NOT GOING WELL!

My poor baby: http://imgur.com/a/z2HRr

My setup: Critical Jack Herer seed, Fox Farms Ocean Forest, Fox Farms Big Bloom, and 8 23w CFLs. 

Things were going well but last week I trimmed and noticed some yellowing leaves.  I figured that I might have over done with my nutes so I just used water for a week now, and it's just getting worse.  It was a few leaves around the bottom that were turning yellow and brown around the edges.  The leaves at the top are starting to curl and get lighter.

I'm questioning everything that I'm doing at this point. What should I do next?
