What did the seeds look like?
if your sure they were marijuana seeds, i dont see why it couldnt be marijuana. its true that i've never seen a sprout like any of those, but im sure tehres some weird strains.. and i heard blueberry-weed grows in a very weird fasion. definitly keep growing them and also definitly keep posting pictures, im interested to see the outcome of these plants. im sorry to hear some people were giving you a hard time on here, but its happned to me too.. heres a pic of some pot seeds. did they look anything like these?
