Sorry...I don't do 'quickly' very well, lol. (speed kills, patience heals)

Providing pictures and filling-out the troubleshooting form will likely get you better responses, but with the info you've provided, I'll give it a go...

My first question is...are these a serious project, or just idle curiosity?

Anyway, if you are talking about the first set of leaves that appears, those are cotelydons. (your baby's first leaves) Round in appearance, but the next set of leaves will show the serrated leaf-edge pattern you are used to seeing.

If this is the case, and you have never seen cannabis seedlings, I'm going to take it for granted that you have shitloads of reading to do if you want to bring the plants all the way to harvest. This isn't rocket science, but you will get better results if you know the basics. The search function on this site works, and there is a FAQ section you should check-out.

If the cotelydons aren't what you were talking about...perhaps someone put nettle seeds in your
schwag a few years back. :thumbsup:
