Older clones are taking the final form so soon will stop with streatching, leave main colas to sprout out from the bushes and expand much more than mothers did. Without any special meticulous symmetry, and topping, to speed up vegetative growth. While no technique was applied on smaller clones, so they can equalize in high with others. Only bending of the tops, so their lower branches can brake through into line with them, forming a bush that way, without deceleration of growth.
