Interesting. My guess would be some other factor was the cause. I know there are varying opinions on what happens when you clone a clone but I do it all the time. I don't keep mother plants. I clone the seed plant then flower the seed plant and take cuts from the clone, then flower the clone and take cuts from its clone. On and on. I am 28 times deep doing this on one strain and there is no difference from the original. I have other strains where I have repeated this process more than 15 times and still no difference. Every once in a while I will get a plant that doesn't look like the others... Either fluffier buds or curlier pistils or something like that. I think to myself, "OK I've reached the limit of this cloning a clone thing and the genetic information has become blurred or contaminated in some way." But then the next generation of the strain is back to normal so I keep on going. I figure there had to be some other reason for the difference, root structure or maybe I cloned a branch with a weakness/disease or something, IDK for sure. I have yet to reach a point where all plants become unrecognizable from the mother, there's just a few oddballs that crop up every once in a while. So this was really a long way of me saying I think there was some other cause for your different looking plants. The process of cloning a clone will work many many times over with no probs.
