My plant is about 2 months old, growing outdoors in a pot. I am unsure of what is on some of the leaves here? I took the best pics I could. I haven’t noticed any bugs on the plant. It looks healthy otherwise as far as I can tell.
The speckling is likely aphids. They punch a tiny hole to suck juice from the plant and it leaves a dot of damage. Squiggle marks can be leaf miners. It's outside expect some random damage. Look under the leaf but odds are your eater got eaten or moved on to a more tasty plant. BNW
