It's tough to tell definitively from the picture, but they look like big female preflowers, the rest of your flowers look too young to believe that any seeds could be present at this time. id guess you're in week 3-4 of flower? I consider it a desirable trait to see that, as it helps identify female plants from normal seed, and personally I find that all plants with big bulbous preflowers have always yielded the best flower. looks like you may have gotten a good one.
