different genetics means different levels of nute they can take without burn
That look's somewhat like OG....Very weird it doesn't carry the smell and packs little punch. It could possibly be a commercial hybrid you got your hands on. Grandaddy Kush maybe? If it doesn't pack a punch or reek of OG, then you likely got a hybrid, and this specific pheno could be expressing the other parent's chemical traits and terpenes.
Just a though. It definitely looks like some decent herb, though!!
