I read that you don't need to re-veg it, just give a healthy dose of Phosphorus to promote new flowers and can expect a second yeild in as little as six weeks. Granted it would be a much smaller yield than the first. I would definitely have to agree with the clone idea or SOG method but right now I only have two small plants about two weeks into flowering and am skeptical about ordering seeds online. I might experiment with this idea and will post pics if I do.
