Lol. Hey, she's absolutely fine. What you are looking at, is you got to it hrs after it fell. And the leafs turn towards the light. It happens in a matter of hrs. You should check your seedlings every 3hrs or sometimes when I feel they are weak. I prop them up with green sponge ties. You have her back up right. She'll be facing towards the light by 12hrs. Don't sweat about it. Your stem is just weak..its very long. Happens if there's a little bit of stretching with a big drop off in light charges?
