maybe its like that because its looking for light , my last seedling i left it next to the window and when i woke up it was like yours because of the sun . If you want it to get straight just put a cfl 10cm above the plant and it will be fine :)

the best thing to do if you have nice seeds , put them in wet paper towel keep it humid , after 1 week the first leaves will come out and thats the time you put it in soil :)
