Re greening....this is done by leaving either a few small buds on the bottom, or if you have any little leaves that are beginning on the bottom of the plant, both will work....Move the plant to 18 to 24 hrs of light, after a couple days fertilize the plant with a grow product, something that is higher in nitrogen. It usually takes a couple weeks or more to see new growth, and usually the plant will grow single leaves or slightly mutated leaves until it is back into full Veg mode! Not all plants respond to this tho....but if its one that is worth keeping its definitely worth the try!!
