what are they? strain?
they are stunted for sure. just at a glance everything looks wet. looks like it has never been anything but wet.
what are they planted in? containers? dirt? what is growing in the last pics pot with no 1?
what type light? how long and how far from them?
what are you feeding? how often?
just to me, they look like they are struggling trying to get the root system going. just a sort of rule of thumb, they wont really grow up top if they dont grow below the dirt. so if they are small like that, the roots might not be able to go much further down because youve created a pond at the bottom of your containers.
just for the next time. start them in a solo cup. make holes in the bottom (i use a lighter, but anything works) fill it and plant your seed (i usually use the paper towel method, then to the cup). then go to bag pots. 1 gal then up to 3 or 5 gal. the solo cups are cheap, and bag pots are not too bad. but a great advantage for a tsmall bit of money.
