Dangit. This is my first hydro, and evidently I'm screwing it up. Attached are 6 pics that show the sorry state of affairs. I've already pruned off several very crispy leaves, which is why the plant looks so sparse. I've tried searching through the problem threads, but I haven't found any pictures that quite match what mine is doing, so I'm asking for help.

Some details: I switched over to 12/12 about a week ago. A couple of weeks ago I went to using distilled water, because my tap water has a god-awful Ph (about 8.0) and I was having to use way too much Ph-down to keep it in check (also the tap water resulted in some light-brown slime starting to form after 5 or 6 days, prompting a complete flush every week). Ph is kept between 5.8 and 6.0. PPM is about 1000. Temps are fine and in check, humidity is probably low but I can't really control that (other than spraying the plant a couple of times a day, which I do). This is a single plant with about 135 actual cfl watts (350w equivalent), at about 10,000 lumens.

Is this nute burn, or is it lock-out? Or a deficiency? And if so, of what? The new growth has always looked good before, but since switching the light to 12/12 there hasn't been any new growth that I can tell.

HELP!
