seedling leaf yellow, curlin

Hello all,

got a two week old seedling under 46 watts (200 watt equivalency) of CFLs in pre-nuted Target organic soil, just transplanted from a small pot of "just add water" soil pellets. She's been doing well, second set of leaves showing for the past few days, but one of the first set of true leaves has been turning yellow/brown in places and was doing so ever so slightly before transplant. The cotyledons are yellowing and curling as well, but I've heard that's supposed to happen. I would conclude it was nute burn but A) I haven't added anything and B) the other three leaves are fine. If it is nute burn, how do I get rid of it (since I can't "stop" adding nutes because I never started) and if it's not, what is it and how do I get rid of that?

Thanks folks. Worried sick about this li'l thang.

I'd add another light. I left my plants alone for a couple of days and came back. The soil was a little dry (even though I watered beforeI left) and one leaf had a brown spot on it. I watered and it was gone within an hour. It was a 2 week plant at the time. so maybe water your pots til runoff?

It also might be nute burn from the soil. Alot of general soil from stores like that will nuke the shit out of your plants.

Did that.

Other leaf of the first set is curling now, too. Pretty sure it's nute burn. So how do I get rid of it if I'm not feeding her right now?

Also, thanks for the response.
