It sounds like the plants are stretching from no enough light... I'm not sure what that other guy is talking about but if the seedling has a 3 inch stem and is just starting to make its true leaves then you need more light. How far is the light source from the plant? How hot does it get? Also I would keep the PPM low until the plants either start Turning yellow or they are about 6 inches tall.

I just started my first cabinet grow two weeks ago (including seed germination time). I have a 20 inch tall PC Case growing box with a 50w HPS growlight and a two plant DWC hydro setup. The seeds (Nothern Lights Special from KC Brains) germinated and sprouted in five days and then I increased the PPM (General Hydroponics Growth) to 250 and kept the light on for 24 hours a day for ten days.
