The only 'hostility' you're sensing is my determination to ensure 'suspect' advice doesn't go through unchallenged. I know you and many others are only trying to help, but sometimes 'suspect' advice can be worse than none at all.

It's impossible to tell if compost/soils have 'organic' nutrients in them or not for a whole variety of reasons. Compost/soil makers don't really want you to know what's in their composts and the term 'Organic' can mean different things to different people in different places due to the confusion over whether something as simple (and obviously organic) as Peat is actually organic or not. Plenty of people do not consider 'peat' to be organic due to the way it's collected from unsustainable resources.

The soil/composts actually labelled and certified as 'organic' (or peat-free) by the administrative authorities that govern it - are usually nothing more than half composted wood chips that have little or no nutrient content in it due to the absence of peat.

This is precisely why it's extremely dangerous to recommend to someone to ensure their compost/soil contains organic nutrients because the possiblity exists that they will be sold 'Organic' peat free compost which is crap for growing any plants in let alone Cannabis.

It's actually better for new growers to stick with tried and proven composts that do contain chemical fertilisers like Vitax Q4, principally because they'll get better results than trying to get to grips with the complexities of organic (or 'peat-free' organic soils, they may end up with) based soils.

100% Organic grows in my opinion do produce the best buds of any growing methodology if grown correctly, but 100% Organic growing has a steep learning curve and the simpler method of growing with chemical based fertiliser soils and chemical based nutrients is easier for new growers due to the immediate availabilty of the nutrients to the plant rather than having to wait for the slower process of organic nutrients to be broken down into plant useable forms - this in my opinion is one of the causes of new growers to over-fertilise their plants because they don't understand the organic growing process.

As you can see, it's all a little more complex than what you might think.

Interesting, I hadn't thought of that, thank you.
