Are you sure you got autos?
edit:
nvm; checked your post.
Something went wrong. They are about the size of 10-day-old plants.
The strong discoloration of the leaves indicates what's up.
I'd guess you used too much fertilizer - too salty.
Also: While totally ok to transplant autos, it's better to plant them in the big pot from the beginning.
