Northern Lights Auto not growing very well

Hi, I germinated my seeds about week ago. After 2 days they were germinated and I put them in 1 liter pots. I have them beside my window, so light is not the problem I think. 2 of them are good. But the third one is not growing well. I think I put too much water and it's a problem. I also post pictures of them, so please help.

they dont look that bad! But definitely the light is not enought! I dont think it gets 18 hours of light per day! maybe Im wrong but also you have to make the humidity high since they have very little roots! Try to spray some ph balanced water without any nutrients and spray the top of the leaves but not too much maybe about 2-3 sprays also check the temp of the leaves if you can. If the lights are not enough but you dont have any grow light try to find the strongest light you have in your house and put your plant under it its better that nothing! Good luck brother

To be honest..If you are relying on the light coming through the window as you primary source of photosynthesis your going to have a problem as its no where near the strength you need..Sure they look fine now,'but as they grownthey will really beging to stretch...Hopefully you can get them
Outside ASAP as the window reflects
much of the light...However, remember to "Harden Off" your plants..."gradually" expose them to Sun or proper light inside as the rapid transition will scorch them as they will be unprepared to deal with large amounts of light.

Hope this helps..

Cheers
