Answer: Cedrus deodara 'Aurea'holds its best color in full sun and needs a well drained soil. It also does best when protected from strong winds, both summer and winter. It is tolerant of a range of pH conditions. New plants may show signs of transplant shock or poor rooting, possibly caused by poor planting technique or incorrect watering or overfertilizing causing "fertilizer burn". There is also a possibility of a pest or disease problem. In general fertilization is not the answer to poor growth in a new plant, it is most likely caused by a stress of some kind and fertilizer-induced growth just increases the stress. I would strongly suggest you consult with the professional nursery staff where you purchased the trees (especially if there is a warranty involved) and/or with your county extension to try to diagnose what is happening with your trees. Once you know that, you can determine how to proceed. You would also want to run some basic soil tests and then if needed, fertilize according to the test results. I hope it is nothing too serious.
