I'm sorry, but you seem to be twisting science around. Cannabis is a plant, it follows the same rules as all the other plants. I suppose a deformity could be caused by stress factors, but is this really a deformity or a reaction to stress. For example over-watering, under-watering, uneven watering, insects, pathogens, could cause simple deformities in the shape of the leaves. Is this what you are talking about? What is most likely happening with the more potent mutants is crossing over. This is a certain type of chromosomal mutation, where the chromosomes cross over. This is how a mutation can cause the same effect more than once, and why some people might see the same mutation DJ short has. Maybe this is the "difference" between your deformity and his mutation. With a double cross over it is possible to achieve the higher potency, but with a 'deformity' in the shape of the leaves.
And to cannatricks, clones of clones should have a HIGHER cloning percentage. Think about plant selection. The cuttings that do not root are tossed out, but the cuttings with faster, better rooting are selected because those are the ones you use.
