Well it's hard to understand what your saying.. But that being said. No. "Deep green" leaves is generally nitrogen toxicity. Narrow leaves is a sign that more of the "sativa" genetic background. Therefor implying if the leaves look dramatically different in size (thin to thick) then they are probably not the same strain/plant.... Blue and purple stems are typical in younger growth and some plants even grow purple and bluish stems throughout their lifecycle. Aka. Genetics.( in some cases tho it can be a problem or a disease .. So you need to know the genetics). But, it has no relation, or can't tell you just because it's purple or blue that it's a "blueberry" strain. Doesn't work like that. It can help in certain strains point you in the right direction, if you know the genetics well enough. But over all, it;s nearly impossible to tell. You have explained (VERY roughly) two different plants. One sounds sativa'ish and one sounds more indica'ish.. Post some pictures and let me take a better look at them and go from there.
