Scute shedding is associated with growth, but the top layer of scutes will not necessarily be shed every time there is growth, especially if the turtle is a hatchling/younger. The seams (lines in between the scutes) of my eastern painted yearlings will periodically turn whitish, indicating that the shell is growing, but as the growth slows, it will darken and become part of the scute, and the shell will be larger. At some point, however, the top layer of the scute will be shed.
Turtles also will shed some skin when they grow, and normally this is seen as translucent wisps of skin hanging off their extremitites/neck/tail while in the water. Heavy shedding (big clumps of skin, shedding more like a snake, for example), for an extended period of time is not normal, however, and could indicate a number of things--too fast a growth, temps (both water and basking) that are too high, a too high ammonia level in the water, even a fungus, to name a few.
