dude thats far too much light for sprouts, i suggest florescent or cfl for seedlings or clones. Also, your pots are too large to for the young sprouts to keep up with. There probably getting over-watered and supplied with too much nutrients, this causes more harm than good for the plants. Start...
your container is too large for the plants, the idea pot size for seedlings and clones are 4 inches. 4 inch pot should be enough for the first few weeks, after that you should transplant. Wait for the sprout leaves to fall off and then transplant to a 2-3 gallon pot.
