We assume that you are providing the same care to both plants in terms of watering and fertilizing. Jade tends to turn lighter with more sun—could the lighter-colored plant be getting more sun than the other?

Additionally, some varieties of jade are simply lighter-colored than others and have different growth patterns, so that could be it, too!
