Pat: I think Michael P has responded about the potential of a mineral deficiency. Also, sometimes pine will exhibit a yellowing of new needles when the rootball is kept too wet. I've seen needles on black pine that are yellow/green at the base and then gradually turn to a darker green as you move out toward the end of the needle. You may want to watch your watering. Also, if there is some of the old field soil around the interior of the rootball, it could be retaining more water than the fresh bonsai soil. Good luck. Paul
