I conjecture that _something_ is lacking. Is it a nutrient? A
trace mineral? Biological activity from symbiotic organisms?
A chemical that helps the plant absorb nutrients already present?
Interesting to hear about your N. macfarlanei as compared to the
others you mentioned. I've witnessed the converse.
Anyway, from the lack of responses I glean that a detailed and
methodical study has not yet been done and published. If such a
study has been carried out privately, then no one is letting on.
