Sounds like genetic Mutation I have seen before Many Times, If I visualize what you are saying right, Two Stems have melded together, into One, if that sounds like it, We call that a Club or Club Foot. When it Buds, it looks so Strange, like an Amoeba Joining Together, or Siamese Twins, the bud it will produce, can really only be used for Personal Smoke, as it does not separate like a Normal Bud!!! You really have to watch them for Mold as well. Because that melding will separate the Bud into two Spheres(LIKE A BRAIN), holds onto moisture really well. I used to Think How Cool They Looked, that I would let them Bud and Get Mature(IF MOLD DID NOT GET THEM), and keep them as kinda Novelty items, and trip out people with them. I noticed that it always seemed to happen with One particular Strain, ATOMIC HAZE. By Dr. Atomic Seeds. The Strain is one of My very favorites to Grow and Smoke, when I was able SMOKE!!! I have never Grown a bad Plant of this Strain, it exhibits a Couple of Phenos as far as Structure goes, but the Smoke, Like the Buds Appearance, Smell, Flavor and High are pretty much the Same. All AAA I might add!!! But this Strain always would have one or two, out of like 3-7 Plants, that would do this every year. After awhile, I would just cut the Arm or Top off as soon as I noticed it was happening!!! Because the Bud looks to weird, and therefore No One wants it, and it ends up becoming Hash Material, or Cannabis Brandy, for Butter and edibles. If You catch it at it's earliest Stage, You can remove it, and the Plant will just fill the area in with something else, maybe not as big as the Club left alone would have been, but with something that you can make better use of. Sorry I could not have answered your guys Questions earlier, Too Hectic around here with My Wife!!! BTW, Dr. ATOMIC SEEDS are KILLER, Cheaper, and always produce magnificent Herb!!! I just got an E-Mail from Him a few days ago, letting Me Know some of the things he is working on. One was a what He called '"A MIND F>>K HAZE" a "Super Lemon Thai" that were both Pollinated with his NL Strain that goes back to the late 80's early 90's. It is an original, of the original NL's, line, just a different Pheno, from the same batch of originals that the first NL came from!?! What a MOUTHFUL. I actually prefer his Pheno to the Original one!!! So if You are interested in his seeds, He sells through mostly Victoria island Seed Co. and several others. He mentioned V.I.S.C. to Me, I think because they get his first and Youngest seeds, or most Viable ones!!! I feel kinda lucky, because he told me I could By pass the SEED Co., and get them directly from Him, I was HUMBLED!!! He is also working on Strains From Africa, Colombia and Thailand, that He Breeds with his original NL Strain. All of the Seeds I have ever grown from Him turn out Awesome. So if You are looking for something new, Good and different, I would check Him out, He is a damn good Breeder. Take care Friends, SINCERELY, JAMESTHEGREEN.PS, it had been about 4-5 years I believe since i last grew his Stock, glad i found Him Again!!! Prattlen, Prattlen, Prattlen!!!
