I have done both, many times. 18/6 is the way to go. But what Ive started doing now is I use 24/0 when seedlings or clones are rooting. Then I switch it to 18/6 after they get about 3 sets of leaves. I have two major isues with 24/0 that made me not use it the entire veg after a few grows. I noticed that the roots seemed alot smaller and filled the 5 gal pot up less then when I had it on 18/6. Also I had a much better F/M ratio when I did not use 24/0 the entire veg. When I did 24/0 i got about 50% - 60% female, and when I did 18/6 it was more like 75% - 80% female. I may have just got lucky, but those are my observations. laterz..
