Look up Google click Images type in flea beetle damage. Also set sticky traps to be sure.

Acid rain!

Have you looked under the leafs? Anything there?

ah wow yes it appears to be Flea beetles! Ill get some food grade DE and spread it around my garden.

thank you!

Before you attack may want to be 100% it's flea beetles, that's why I mentioned sticky traps. I always want to know what's wrong before trying to attack or resolve some other non pest related issue like nute or soil difficiency.

Slow down!

As habjolokia said, before you attack know what you're dealing with.

Frankly, from your pictures, I'm not sure it's a pest. Besides the holes you have some malformed leaves, yellowing leaves and dieing leaf tips. To me at least, it suggests it may be an environmental or nutritional issue.

Put out some traps as suggested.

Agree with Ottawapepper, could you post pics of the plants in their current state? Would be helpful and describe the conditions temps/watering/ferts
