did you wet trowel? sounds to me like the trowel was skipping across the surface - if its left a series of ridges then thats the cause. you can sand or refill with a fine surface filler.

these ridges can also be caused by trying to trowl up to soon or going over it to often as this pulls moisture to the surface.
