Yeah, 24/0 is ok for the first week or two, but then your plant really needs a dark cycle. Makes it feel like its mother nature controlling it, and that what your trying to simulate inside. Its look good but just like AC420 said you really should get a fan to blow a gentle breeze on them. It will make the stem stronger, and that way it wont fall over under the weight of the bud.

In the dark cycle you could also try misting the leaves with water, because that will also strengthen them at the same time as the fan doing the stem.

Good luck!
