Plant Problem! Need Help FAST with pics

hey guys, I am wondering why the leaves are curling. I am not sure what the defiency is. If you can also see the one plant is stretched out like a mother fucker, but the lowest leaves have turned yellow and the curling is really concerning. The stretching is because the lights to far away and it seems as if it needs more lighting. I dunno. If anyone has any input please post. Thanks

P.S. - This would be my first time doing an experiment like this if i did it.

Looks like overwatering or overfert. Its too young for nutes and it has to dry before you re-water. If you allready fertilized then flush after it drys then use water only for a while.

Bubba Kushman is right.
It looks like simply too much water.

overfert can cause that leaf contortion. if there are nutes in the soil I wouldnt flush just leave em be they will work through it. and i wouldnt feed them either. that last pic look like she is a bit older and can actually start getting nutes at 1/4 dosage-is she really that almost neon green or is that the lighting. that lower yleaf yellowing means she needs to be fed.

In other words, Don't do nothing yet except maybe sweet talk her a little bit.
Post another pic in two days or so we'll know more then.
Don't water her untill the soil is good and dry, let those roots breathe, it won't hurt her.

ya way too much water look at the dirt in the pic its soaked let it dry out a little and move the light nice and close dont add any more nuitrents and when shes dry flush her good (run it under water letting it run out the bottom till its flushed)u should stick ur finger in the dirt about an inch if its dry then water if its moist dont water and wait till there about 12 inches then start the nuits. if ur growing with cfls then get that light an inch away from it
