Unidentified plant/weed in new lawn

Hi everyone, im at my wits end trying to identify this plant that’s currently taking over my newly seeded lawn… i killed offthe old lawn, put new top soil over it (“weed free”) along with seed etc and along with the grass is an infestation of these plants. 
Ive tried using a plant app that identifies plants based on photos but the accuracy percentage was under 10% which meant its not accurate… ive tried everything in google and nothing. 

So hopefully someone on here knows what they are and more importantly how to kill them without killing the grass. Thanks. 

Btw, they grow in clusters at the back and all down the one side

  • @joshuaagodwin1998RVIvQ2tq If you have them on one side "only", don't care about the lawn, but take out the entire area, and start from scratch. As you said, they regrow and this will happen when the lawn is out.

    They look like the stuff that I have in my garden. I think my ones come from the Borage that I had, but it might be something else. The leave feel a bit velvety like from young Borage seedlings.
    We had for months no proper rain and the recent rain made a lot of seeds obviously germinating. I'm currently busy with taking them out in the garden.

    Most of the leaves are the first pair of leaves from the germinated seed and are called cotyledons, eventually they die away when the true plant leaves grow so until they do it's difficult to say what the plants are. That's why you couldn't id the plants with your plant app.
    They could be cleavers, commonly called goose grass aka sticky willy or they could be chick weed but that's just a guess.
    The ferny type leaf is a wild flower called herb robert. 
    Suggest you wait a few days when the newly emerged leaves have grown and then you'll be able to id the plants properly.

  • My lawn has patches like that appearing near the flower beds and borders … they’re where my aquilegias, foxgloves, rudbeckia and all the other flowers that bloomed earlier in the summer have dropped seeds. 

    I think yours will be seedlings from something nearby. 

    When you mow the grass you’ll take the growing point off these and most of them will die. Any that survive shouldn’t be too much of a problem to get rid of at a later date.
