Neither one of my new seedlings seem to be doing very well. This one isnt as brown as the other but its leaves are starting to curl. There still ridged but are curling up.
Based on information in your week one post you could be looking at heat stress, for such young autos you could raise your lights pretty high on them(even 30-40ins above), id suggest keeping your temperature a bit lower around 24-26 and see how they like it!
