As I've stated in another thread, cannabis has a lot in common with wines.And just like subtle changes, sometimes very subtle changes, make marked differences in wines, terpenes also play a role in the psychoactive properties of cannabis, and oft times they're just as subtle, if not moreso.When it comes to cannabis nutrients during growth, there are two schools of thought. One is that all the marketing material spouted by the extremely profitable cannabis nutrient industry is the gospel truth, and super-blaster-mega-9000 will really make your buds explode with growth and flavour. The other school of thought is if you pick up some $30 10 lb sacks of NPK, and a few trace elements and minerals, nothing else is needed and the commercial offerings are nothing more than 'rocket-fuel' bullshit. As usual, the truth lies somewhere in the middle.While the cannabanoid ratios are genotypically variant across phenotypes, you can get slight - and I mean parts per million slight - differences in terpene ratios with different nutrients. This even though by the 'on the label and by the mix' metrics they have the technically same NPK components, the variations in trace constituents seems to affect the terpene ratios significantly.That's why sometimes you will get two samples of the same weed grown by different gardners that test out to the same cannabanoid ratios, but have noticeably different effects.The demonization of cannabis for so many years has held back research, and we're lucky as fuck to have someone like DigialtAlch on board here that is studying and gaining a deeper understanding of the complexities of the worlds most versatile plant. It's an exciting field now, and over the next decade as we learn more about cannabis we're going to be absolutely amazed at the incredibly wide range of facets that cannabis presents.
