It may be impossible to tell which one but perhaps eliminate? I've been looking at some youtube videos of people claiming they are growing og kush and the leaves are much narrower on theirs...
Unfortunately no two plants are the same, especially if it's a hybrid. I've grown 2 plants of the same strain before and they were both completely different. Good luck.
Even with a stable strain there are about a dozen or so subgroups called phenotypes that it could turn out to be. They're just different genetic expressions of the same plant.
Same as mick its impossible to tell honestly the saying seen one seen all is quite true I have 2 gelat.og in flower right now and the differences between them both is laughable.
