I would ditch that plant. Its stunted.

Put the sprouted seedlings under light now, where have you currently got them? Also put them in small pots and transplant when needed.

If you have 6 places for bulbs, use them all! Do something like 5 x 6500k (or 5500k if that is what you have) and 1 2700k for veg stage and vice versa for flowering - the stronger the wattage the better (more lumens) but make sure its the correct kelvins for the stage you want. Do keep your Light on and off times deadly accurate and get no light in with them at "night" - Don't even check on them during this time just to make sure.
