In Australia I am using the earlier version of this organic fertiliser ( I still have bags left over from bulk purchase )
https://www.nutri-tech.com.au/factsheets/life-force-gold-pellets.pdfIf you look at the analysis, it is a reasonable match for the conventional fertilisers in this post.
The NPK is reasonably close, but the N is a lot lower and the K is a bit lower.
In organic methods, that would be assumed to be ok for several reasons.
The application rate for pots is 15g per litre, so a 50 litre pot needs 750g, and that supplies 3 % N.
To get a higher whack of N you need to add more, plus you are also adding all the other nutrients too.
You will hit a point of physically adding too much fine fertiliser to your pot, causing surface matting crusting problems.
Of course you can get around this be adding less more frequently, or incorporating better deeper into the pot mix.
Personally for containers I found it better to use this type of fertiliser and a conventional type to get the NPK up.
The high NPK fertilisers also cause problems, fertiliser companies also often sell insecticides and fungicides to control problems linked to fast plant growth rates.
There can be high rates of leaching of soluble nutrients or vaporisation of N from conventional fertilisers. You may not get the full benefit of whats in the bag.
