What lights are you using? You say 50w cfls. Is that equiv. or actual? What spectrum? How close to the plants are they? What soil? What water (tap...well...distilled...blah blah blah). How often are you watering? What is the temp and humidity? What are you feeding them (if anything...I don't feed first 2-3 weeks). Do you have any airflow over them?
Seriously, there are too many variables unanswered to just look at the pictures and be like "Oh you are using miracle grow, your lights are too high, the temps are too high, there is no air movement, you are overwatering/underwatering, the moon and jupiter aren't aligned properly.......". You have to basically layout everything you are or aren't doing in order to get some good feedback as to what needs to be adjusted or changed.
And yes, they aren't looking too good right now. But they aren't a loss right now either. I advised earlier that autos like either 20/4 or 24/0. It won't hurt the other to be under that during veg either. But you stayed with 18/6 so I'm not really sure how much other advise you are going to follow. Post up answers to questions people ask about your grow and it'll help them to better help you.
