There is a little merit to this guys argument. You have to go back further than just the mother plant, but it is possible for plants to develop feeding habits over generations.

Nutrient sensitive plants are common in genetics weakened by what is know as "inbreeding depression": repeated self-breeding and inbreeding. They are also common among strains created by poor breeding and seed production practices such as random crosses and pollination, inferior parent selection, low quality control, etc. In addition, long-term hydroponic generations gradually become genetically conditioned to grow under synthetic feeding and start to loose certain abilities in self-sufficiency. Unfortunately, a substantial amount of mainstream strains fall under these categories. Nutrient sensitive plants do not have the natural ability for fast and vigorous growth and require long vegetative growth periods for their development, root development is slow or insufficient, they do not grow abundantly in soil without extra feedings, and so on. Many nutrient sensitive plants do not perform satisfactorily unless they are grown hydroponically and may require high nutrient levels. On the other hand, such strains/plants tend to be finicky. They may constantly alternate between showing deficiencies and symptoms of over-fertilization, or both at the same time.
