Plants yellowing

I need some help! I have a hydro with some nice seedlings that have been growing nice for 11 days. They started yellowing a few days ago and I don't know why. At first it was only 1 plant now there are about 5 out of 12.

I read that if may be lack of nitrogen or molybedn (something like that) and I have added some but not sure on how much I should use for my 13 gallon hydro.

Check out the pics and please advise.

And they're stretching a bit, so some more light would be good...

What's your PH and PPM at? It doesn't seem like one thing in general, more like maybe a lack of nutes. Anyone giving you a direct answer without knowing crap about your situation, well I just don't get how they could know whats wrong if you haven't given anything other then a pic. Are you even feeding them yet? You should be at least 150-300 PPM if they have roots and are already in your hydro setup.

Again unless I'm missing a big part of your post I don't see any info on feedings or what your status is at all. IMO you need to give more info to get any accurate answers from anyone on this or any site. So that said my GUESS once again is lack of nutes in general. If your not already at 150-300 PPM get there and you'll be happy once again. Oh and make sure PH is between 5.5 - 5.8 EVERYDAY as that will mess everything up faster then it started if off up or down!!! GL

Actually, I could tell it was stretching from one pic...

Greater amounts of information are generally given/asked for as the thread trundles along, in my experience anyways

Tell us everything you would want to know if someone asked you this question.
We can't give answers with no info.
Ya, it looks like it COULD be any of one or more deficiencies, but without knowing what the plant has, doesn't have, we're in the dark.
They look too young to feed, but it could be anything causing this.
