It is not genetic. It comes from a change in light...either type..cfl to hps to outdoor, or intensity...indoor to outdoor. Changing the light cycle will make leaves "spin or curl" they will grow out of it. They need consistant conditions. Most people blame genetics when it simply is an oversight, like you are dealing with. Keep the plant in the same spot, and try to be consitant with time and feeding schedules to get the best results. If you ever have to pull a plant out of flower and put it back into veg cycle, then you will know what I mean...single leaf growth versus the 5 fingered leaves we are used to seeing...bottom line your are fine. keep em in or keep em out! It takes a few weeks to correct itself, and moving them back and forth will only prolong the problem. good luck.
