its hard to say what caused it, but ive had a very simmilar thing happen with a plant grown from seed, the plant "recovered" and became normal with new growth.my money is on it being some kind of genetic mutant lol, but with it being a clone and the others not affected....strange.....

maybe stress and/or the fert applied unique to that clone combined with its particular genetics is causing it? a freak accident, like spiderman lol

...pass...
