I have found that my plants grow faster when the light is on 24/7. IMO i don't think that is the reason for your plants growing slow.

unix...you may notice what "appears" to be a growth spurt, faster growth under 18/6, but IMHO, it isn't actually faster growth, but more stretching searching for light. This equals more distance between nodes, not more growth.

"I" prefer 24/0 for vegging under flourescents, but I also like to give the light and ballast a few hours of rest and cooling period when I go to the HID.. So I usually revert to 20/4 or 18/6.
