Is this a nutrient/water/pH issue, or a pest of some sort?

Not an expert by any means, but that looks like a nutrient or sunlight problem of some kind.... I don't think it's a pest.

did you get frost?

that's what the edges of my lettuce look like

or my brussel sprout leaves - some of htem look like that - and honestly, i didn't water much this fall - i got real lazy so i think they were thirsty - but htey still produced.

i'd just cut off that bit and eat the good parts.

Looking at that, as a fellow indoor gardener, I think it's either sunburn or not enough light. Possibly the leaves were wet on a bright day and got burned by focused sun rays, or possibly they were dry and too far from enough light. Although, unless you cut them pretty high up the stems, they don't look leggy to me, which would mean maybe they did get sunburned.

If it's neither of those then it's probably a nutrient problem. Try adding easy things like watered-down milk (calcium) or coffee grounds (nitrogen) to the soil and see if it improves.

maybe 16 hrs a day of high powered flourescent light is too much? Some of my spinach has the same look.

I think that probably is too much. Try bumping it back to 12 hours or even 8.
