I don't mean to do a product placement but switch to scotts soil with perlite at least or foxfarms if you can.
MORE LIGHTS!
What is your pH anyways?

yea. it looks like a nutriet deficiency. ive found tomato food miracle grow to be the best cheap and easy to find nute. start off with a quarter strength mixture though, so you dont give them nute burn. also invest in some higher wattage cfls

a nutrient deficiency or to much nute can stunt growth, as well as underwatering, and a too low or high ph, and also if the plant is indoor the lighting may not be strong enough.

Im 100% sure its either a deffiency or ph imbalance locking out a nute.

Change your soil and start over

how far have you been keeping the lights from the plants. if there further than two inches from the tops of the plant then there not getting enough light. pH shouldnt be a problem unless youve been fertilizing. dont fertilize in the first three to four weeks. i would add lights. are there any nutes in the soil already. if so then its not a dificiency. plants that young dont usually have dificiencies because they dont need much at all to get to that point.
