Eventually you need some phosphorous since ammonia does not help there. Some carbon and sulfur too in an amount that nobody can quantify. Along these lines, the trend of dry/dead rock can supply some of this, but unclear if it is in a super available form.
This might be too old-cycle, but the juices from frozen food were a strong go-to.
