I think they may make it... Should I trim?

I bought some Scott's soil and germinated three different types of good bagseed(I always save the really nice looking ones from good smoke) and after 4 days they all popped up. Was doing good till the first water and it hit em pretty good. No Scotts anymore. Local store has FoxFarms I found out so waiting on them to get spring shipment. Anyways, the first set of leaves got nute burn( 1 bad, 2 mild, 1 seems to be handling the high nutes just fine) Should I trim the dead end of the first leaves off? Please take a look and let me know your feelings as the last 3 days they started shooting out many small beginnings of leaves and I don't want to stunt the one plant I want to do. The other three are fine I think.

Ok, I can't seem to link the URL on these pics so here are the direct links. At least till I figure out how to get the image stuff to work. I just really want to know if i need to remove the two leaves on the one bad plant.

BTT .. Plants are starting to take off and those two leaves are about all the way yellow/dead now. Should i get rid of them?

This one:



The leaves on these are fine i think.

Ok, my custom light fell and squashed one completely, burnt the side of to of them, and totally stunted the last one. It,s been five days or so since it happened. Two are fine but the third one just looks like crap and has hardly grown. I'm sure the light sitting directly on them prob did it. The third plant was also a very intolerant strain anyways and doesn't handle any stress at all. still will grow it out though if it's a female.
