transplants not growing ?

i germinated the seeds in a propagator and when they had first set of leaves i transplanted into pots but now they havin grown in about 3-4 days i know they take time to wake up but wud they be strong enough to survive d shock i have four burmese kusk and even ones leaves are yellowing like wot nute burns looks like but had not given any nutes just special pre mixed soil i bought from a grow shop.Have these also been killed in action or cud they still come back
its my first grow and have already screwed up once this month i hope i have not done it again but if i have il just have 2 live n learn. Any feedback wil be much appreciated i have no practical support in real life so the nets all iv got thanks

oh yea the other 3 still look healthy

What medium did you germ the seeds in? Are there any nutes in the "special soil"? My guess is it will have some in it, they normally do from growshops. What light are you using, how far behind is the one with problems? W
