You havnt even got pistilles yet?

Damn, something is definatly up. Its gotta be the light, just has to be.

Is the cab sealed?

If they're are any light leaks seal it all up asap cos the dark cycle needs to be uninterrupted. That's how the plant buds, it measures the time of uninterrupted dreakness.

By now you should be budding, other than the light times i dont know what to say.
