How are my seedlings doing?

Hi Guys. Perhaps I'm over-worrying but there is one seedling in particular that I'm worried about, she's growing a bit slantways and can't seem to get upright. I've tried to sort of prop it up but it doesn't seem to be working. I was just curious how they're doing in comparison to other people's. The seeds started germinating about 6 days ago. The real tall one looks like it was stretching for light so I moved them all closer to the tubes.

Thanks! Any feedback is most (rep+) appreciated!
