Everything looks pretty normal to me, Brian. Once you get them 'up', they're pretty doggone durable. You'll get pretty good bulb growth between now and November. Did you recently add the gravel as a topping for moisture and temperature control?
Edit added: I wanted to add that seedlings started outside are always 'shorter and stiffer' than those grown under lights, plus, those started inside have to be conditioned or 'hardened up' when moved outside. You balcony has its' benefits--you sure don't have to worry about slugs, snails, gophers and bunnies. So, I'd say if this is your first time seeding; well, then, you're doing a very good job! As time goes on keep posting your progress with these. And if any questions come up, don't be bashful about asking!
