There are several possible fairly common causes, including overwatering/poor drainage, over fertilization, and insect infestation -- check the foliage including the undersides very carefully for signs of mites or the like. One additional possibility is accidental spray or chemical drift from herbicides applied nearby. Also, newly planted clematis often take a year or two or three to settle in and bloom well, and the new growth does tend to be pale at first. The old adage is "First year they sleep, second year they creep, thrid year they leap." Good luck with your clematis!
