How about a little background information?
It appears that you're using DWC.

I posted more pics a few days before this post, but I guess I named the post wrong and received no hits on it. Look a few days back under "tomato leaf pics??" and you'll see the background info. I have since flushed the system with ph'ed water and lowered the nutes. I thought they might be getting to much fert.
Thanks for the help,

Oh. I purposely didn't get into that discussion, because I use sunlight only. I haven't a clue when it comes to artificial lighting. Not that it matters now, but at first glance, it looked to me like maybe a light problem.
