my babys are pitiful

so i started my plants off using the paper towl method, grew them in pots in my room for about a week, and then transplanted them to much bigger pots out in my woods. im using composted horse shit which i guess is a good fertilizer, because all my parents friends come to shovel it into buckets for their gardens.

and so now its been like somewhere between one and two weeks and they still look the same as when i put them in. theyre like 3 week old plants and some are only about 2 inches high, with one pair of leaves with ridges and that one pair of smooth round leaves. a couple have started to grow more leaves but are still pretty small and flimsy.

im thinking that maybe i stunted their growth when i transplanted them. if i did, when would they continue growing again?
or is this normal?
any help and advice would be greatly appreciated.
