    Infrequent agitation is all right, but there has to be a source of fresh developer. If the hangers are too close together and/or the overall volume of developer is low, there won't be adequate fresh developer reaching the film and/or it will not be uniformly distributed. The same will be true of stop bath, fixer, etc.

    The tank needs to be larger and/or the hangers need to be further apart and/or agitation needs to be more frequent.
