Plant id please

[SheWoreYellow]

I planted seeds but I think this is a weed. PlantSnap id says it’s a peach tree. It’s not.
What do you think?
Seeds I planted are cosmos, lobelia and gypsophila. I don’t think it looks like cosmos or lobelia. Any chance it could be gypsophila?

Can’t see a pic, sorry.

Forgot the pic

The Picture This app thinks it's a Fig-leaved goosefoot.

My gypsophila are much purer green leaves than that.

I thought Chenopodium (goosefoot) but the leaves don't look mealy enough

Sounds like a weed, then so I’ll remove it and give room to the rest.

Thanks!
