Aaron -
Needle the element of teh depth that is either excess or deficient. Ie - there is no root, the water area of the depths is absent. Needle the water point on that channel close to the bone.

Will, when you say needle the corresponding element on the channel, do you mean needle the mother pt. of the effected channel, and then needle at the depth that which you have found the excess or deficiency? Thanks, Aaron
