What is getting my sweet peas (picture included)

Any ideas what this is?

🤔Anyone

It looks like damage from a veery small insect called a leaf minor.
id cut my losses and buy some seedings from a garden centre and plant them directly outside in the ground.

Leaf miner. (Not a leaf minor with the awful implication that there’s a leaf major lurking around the corner Sorry Bumble, not getting at you, just helps with googling if the spelling is right)

Perfectly fine Mere I should have checked.🤣

Thank you both. That’s really helpful. Have found it on Google and ordered some spray - it was hard to track down a treatment!
