Mmkay. Does anyone still say that anymore? Anyways, I'm kinda confused as to whether you've started flowering or not. More info would be great, and pictures would be fantastic.

I, personally, don't think the water would do anything, but I've never tried it, so what the hell do I know?

Has to be 12/12. If it was 6 here, 6 there, then it would be 6/6/6/6, not 12/12. Besides, I think that would be a lot of differences in light for your plant to handle. I think it would be best to stick with the basics. The 12/12's just harvesting, though. That's what tells your plants to switch into flowering. Has to do with a build-up of chemicals or something.

A lot of people switch to flowering at one foot. Make sure you switch to a bigger pot when you start flowering though, because you plants can double to triple in height.
