Also you should have kept the myc in the jars until it starts to slightly constrict/shrink and you see primordia forming(ie little dots)

That would help drastically

But i completley agree with Mustleid's quote. Even if you shot up the same jars, with the same syringe OF SPORES, and everything about the jars is completley the same, completley different parts (i forgot the proper word, strains maybe???) of the mycelium would colonize in the different jars. Every spore when using multispore syringes is different and carrie different genetics

Each of your jars may very well contain fairly different genetics, if you started with spores
