Aliens have been probing!
Seriously though, often these blemishes occur for no reason, are not a sign of anything or some other issue, they are just weird leaves.
Unless you can find any bugs eating them, I would not be too concerned, they will just happen from time to time.
Remember too, no plant will ever have 100% perfect leaves, 100% of the time.
To me they don't appear to be bug eaten or made by anything, just slightly deformed leaves and these can often occur when the plant is in the rapid vegetative phase, as if it is growing so fast that it "forgets" to finish one leaf properly before starting to grow the next leaf/leaves.
I don't think you need to worry about them and your plant does not need any spraying or any type of "rescuing".
Hope this helps, Organoman.
