Jalapeno plant disease

[Izsak]

Hi,
 
I'm just raising my first jalapeno plants and recently realized some strange patterns appearing on some of their leaves (see pic attached).
 
Can you tell please what are those patterns, whether it is something serious problem and how can I save my plants?
 
Thank you for your answers in advance.

 
Regards
Izsak

Looks like leaf miners. They are a pest, not a disease.

And a fairly harmless pest at that.  Unless you've got a lot of the buggers, the damage looks far worse than it is.
