Hi
@Shinsimilla! I see two possibilities here: either it's a pest-related issue, or it's nothing to worry about. I've seen this kind of mutation a few times in my previous run and in other diaries, and it was a natural genetic peculiarity affecting the first leaves, then it disappeared as the plant grew up. But in other situations, this could come from insects, especially thrips and/or leaf-miners. You should establish a pest-prevention strategy while she's in veg (by diffusing essential oils, spraying neem oil, deploying ladybugs or any relevant solution to repel all unwanted invaders). Take a deep look onto and below the leaves with a magnifier, look for thrips or any insects, if you don't see anything then it's the 1st option, you can relax and watch the new leaves grow without spots/marks. But the pest prevention strategy remains relevant! Hope this will help, let me know in the comments section if you need anything, and how it evolves with time. Happy growing! ๐
