Looks good, Sky. Pretty cool mini drip ring you made. For me, I like to hand water in veg. If you decide you don't want to mess with the auto feeder for the top cabinet, you could always use a drip tray, (like the kind that goes under a planter), or use a bucket lid, and then when you hand water, a little will collect in the tray, and then the plant will take up that extra throughout the day. I do it this way a lot. It's so simple and works great.
I'm 99% sure the spots on your lower leaves are from nutrients splashing on the leaves, drying, and dehydrating little spots. Nothing to worry about at all. I would keep the PPM at 500 or below right now, and you won't have to worry about dehydrating any leaves.
Looking a little droopy in those pictures... I'm assuming that's because it was close to bedtime when you took these pictures? I would be tempted to take the terminal shoot off those two tallest branches, and then start 12/12. You will be surprised how big it will get!
When are you starting flower?
Do you have another seedling behind the scene?
