Trouble with plant Identification

[gardenhooper]

So my partner and I are rookie gardeners and are learning the ins and outs of organic gardening and experimenting with everything we find out. The one mistake I have made and need to clear up is to find out what these seedlings are in my wicking bed. I am not sure if they are seeds that I planted myself or from our compost pile. Please help!

They look like sweet potato leaves to me. Did you plant slips or possibly toss spoiled ones in the compost pile?

We did not intentionally plant sweet potatoes, though we do eat and compost a lot of it. I thought sweet potato slips were heart shaped? Do you have an image that I may reference?

In this post from a while ago,

I attached photos of sweet potato slips and you can see one variety has heart shaped leaves but the other one has leaf shapes similar to plants in your photo.

What do you think?

Oh! I know! -- I believe you can tell if they are sweet potatoes by breaking/cutting off a leaf or stem. Sweet potato should have milky white sap.
