Several have used guano.
Several use worm castings.
The soil is better with organics due to the carbon sources added, NPK alone is not much and does not foster and diversed community of bacteria and by products of their metabolism.
This can impact different taste etc .
Ecologically this is better and from many folk's taste buds it does also.
But farming, the rawness of of it, the inorganic ferts tend to be the best.
For our tanks, well, we have a fair amount of carbon from the plants/mulm accumulation is fine initially but as things get gooey and dirty, we do not want "mud" like a terrestrial system.
So in organic ferts work well, they are also easy to test for and measure and are bioavailable, whereas many organic ferts are broken down slowly etc.
This makes them very hard to measure and needing different test methods to do so.
I toyed with the idea of oerganic ferts for planted tanks about 5 years ago.
But non CO2 tanks do this well as it is.
You will get the best results by adding a bit of both in there.
As we do anyway(unless you have no shrimp, snails, fish etc).
Of course many of you love to herbicides(simazine, copper, peroxide, bleach etc)
I generally don't unless it's on non living equipment etc.
