I don't think it reveg I think it's a mutation I just don't see any signs of flowering usually when something reveg it has signs of flowers idk looks like a weird mutation hard to tell if there are signs of flower from this picture the lower leafs wouldn't have revegged because autoflowers don't usually flower from day one they veg for at least a week, 20 days seems average so the lower leafs wouldn't show signs of reveg. Yeah I think its a weird mutation curious if it produces flower.
