dont know why but i dod it, if you believe it there where still no roots looking out of the roockwool cube so no problem replaceing her substrate. got a little nutrientlock by too mutch ph and no upper or downer at start.
i think they are way behind in terms of flowering . Looking a way off harvest if im honest . These autos dont take kindly to too much defoliation . I hope the buds start to form heavy for you :)
