Whats wrong?

Growing under 1000 watt.Three weeks old and look the same size two weeks ago.Starting on there third leaf,but the second leaf is no getting any bigger.The strain i have is chrystal,had good luck like last time but not this time.Leaves are burning also,and i have not given any plant food to cause them to burn.They are in a 5 gallon bucket and well vented.They are about 2 inches or smaller and are three weeks old from the time they sprouted threw the soil.

 

How close is the light?

Type of soil?

 

yer ur light is maybe too powerfull for the distance ur growing at if i wer u i wud try find sumwer they can use natural sunlight to get em on there way

 

sounds like your light is to strong for such young plants you should either move it few feet away from the tops of the plants (watch heat also) or use compact fluorescent bulb(s) they have a much softer light and young plants love it
