This plant...bag seed gal...starting at the top leaves...has developed a purple color all the way down into the main stem...plant appears completely healthy...flourishing at the beginning of week5 (flowering)...mm wide white hairs and crystal formations beginning at dozens of budding sights...wondering if she will have purple buds...so far the color is confined to the stem...I think it is a sigh the plant is reaching maturity...all I can say is read all you want...do it and the future knowledge gained is invaluable...thats all right now...peace
