Off white line swirls on broccoli and kale leaves?

[Lathy]

This is my first year of organic gardening or growing anything in general . I have learned so much already but I'm pretty much clueless right now when it comes to learning diseases and other problems that have been occurring which leads me to the kale and broccoli leaves. Below is a link for the imagines of both the leaves that have these odd swirl lines near and around the tips:

Thank you for any tips or recommendation !

The squiggly lines are caused by leaf miners, a fly larvae. Leaf miners are a minor problem and mostly cosmetic. Look at the end of the trail and if you see a little bump, squish it. Infested leaves can be picked off if they are not needed.

I noticed that when I delete images from my computer. The links disappear as well. I saw the image earlier, but now there is only an error message.
