Well the only ways i know of to reduce Copper 2+ to elementary copper is eitjer by electrolysis or by deposition on a less noble metal, as zinc, iron etc. deposition usually results in an uneven porous surface that won't conduct well. As for ascorbic acid, or any reducing agent, you will most likely only be able to reduce Copper sulfate only to its Copper 1+ form, just a different salt, really.
nevertheless, the color you describe could be of some metallic Copper precipitating. but the same porous structure is to be expected and that may be the reason of the high resitance
