Well, the seedling didn't make it. Guess it's time to try again. Thanks to those that offered advice.

pardon mate, i missed this one! damn tag by Yeat's didn't work,.. wouldn't have mattered anyway, it looks like the tap root failed,..maybe fungal, or got too dry,... best thing to do is keep the pot overall fairly moist, likely won't need much actual watering for a while initially.. keep the zone around the seedling evenly moist, with some light surface drying in between misting; make sure there's good air circ', and don't mist during dark hours,...

No worries! I don't know if there was much that could be done about it at that point anyway, so a least I'll know for next time. And yeah, when I realized it was probably toast I pulled it from the soil to have a look, and there was virtually no root system. What there was of the taproot seemed to be quite close to the surface, which makes me think that whatever water I was giving it wasn't sufficient. Like it was having to stay shallow and not branch much because the only water was on the surface. Does that sound right, or am I way off base? Also, the second plant I had going that broke the surface just a day or two before I called the one in my OP a failure was not growing upright - but almost horizontal to the soil, with the same super shallow taproot situation. Granted it was much younger, but it just looked sickly as well, so I pulled it.
Things I think could have been done better/smarter:
My airflow was good for the first few days - I had a battery powered fan in there, but it died maybe three days in, and I hadn't been able to replace it so I let it ride. I'll be swapping it for a proper plug-in fan for the next grow.
I also kicked on the second LED about halfway through the week when it looked like the seedling was doing well. It caused temps to jump from a solid 77 to about 84, with a couple random spikes to 90 overnight for some reason. I'm guessing that didn't help things.
I have one more seed germinating in a cup of water right now - it's been there about 12 hrs, and no taproot yet. When it pops, I was going to start it in a dixie cup and take my chances transplanting to the larger pot when it's grown some. I feel like putting it under CFL's for the first few weeks will give me a better chance to control the heat and environment for the first little bit of it's life.

...not sure about the tap root going sideways, but I've heard of that happening before... it'd have to be waaaay too dry an inch or two down, or whatever the depth the root was when it went sideways; sometimes seeds just don't set, but if it's happened twice in a row, somethings most likely off with the germ'ing process and pot set up you follow. How deep do you sow the seeds? there are several ways to do germ'ing right, it's a personal choice really, I've tried several and none stand out above the others for success, folks just find what works for them... 2-3 days ahead of time, I like to set up their pots (generally I see no need to start in smaller pot with auto's, unless they're reg's ); mix up the soil with inoculants and moisten up well, then let them sit in normal grow temps while seeds soak and germ',... I put the seeds in shallow water (1/2" is fine) overnight, or until they sink (poke at floaters next morning, they may sink or need a bit more time)... Then make your hole with something narrow, I go 1cm or so deep (less than 1/2")... use forceps/tweezers to pick seed up and rest horizontally if possible, cover and tap lightly; it takes 2-4 days usually for them to start showing; I mist to keep surface consistently evenly moist... I don't cover them with bags or clear cups since the RH is in good range normally for me (about 50-60%) ... Some folks doing the paper towel method, in or out of a baggie, like to let the tap root get 1"+ long before planting; that's fine, but it risks damage to root,...
Transplanting is okay, but it's a learned skill to know when and do it without damage to roots, so if using fem's, why bother? little cups dry super fast too, so you'll see no improvement there with that,... CFL's are fine, if they have the right color spectrum, otherwise, use what does; they don't need the intensity at first either, so reduce that,...
