Ok bro, it loks like you have mite problem.
Go into your garden and pick 5 of the most damaged leafs and bring them into your house for some decent pictures.
Usually the ones on the bottom of the plant are the most damaged.
Then try analyze the under side of the leaf because that is where you will see them.
They will look like little dots and will move when you touch them.
Send some pics regardless and we will see if you can solve this quickly to get them healthy again.
