Same seeds WAY different seedlings

i used all the same bag seeds (supplemental to my TOP44 and Mandolin grow) and some have VERY wide leaves and some very thin. Is this normal at the 2-3 week stages? Only one set of leaves so far will post pics soon (within a wqeek or so)

mixed phenotypes.... the thin leafed ones are sativa dom, the thick leafed ones are indica dom.
it means the bagseeds were an unstable hybrid

thx so much.
