Hey there, bro! 👋 It's hard to say for sure what this is right now, there are too few signs to determine. The first and fourth photos look like a small scratch on the leaves that you might have accidentally made yourself. There are no clear signs of a problem yet, so don't rush to do anything, don't worry, find some patience and it will pay off in the future, bro! 👌😇👍 Good luck!
