Rock I'd back way down on your numbers....you seem to be having some sort of lockout thing going on.....I'd take them back down to 1000 as macros suggested.

Perhaps its your lighting.....but alot of the leaves seem darker in the middle than on the edges. I would seriously doubt a deficiency......especially at those numbers so I would suspect too much of one thing is starting to lock something else out.

PS...your funky edges also suggest overnute as well.

Good luck.
