It might be some kind of pest attacking your leaves. Have you done a loop inspection of the underside of this leaf? Look very closely for thrips and spider mites especially...

eliminating spider mites

I have tried several things here and there nothing seems to hold the mites off for long. Is this something that needs to be continually done like spraying every 3 days or so? I as m new to this, looking for a little bit of advice. Thanks in advance!

Ok, so with them being outside I’m going to strongly advise you to pick up a few pesticides to use.
Consider the Bees before you spray anything.
i use “plant therapy” and “neem oil” on my outdoor garden. As far as I know both of these are safe for bees but will kill the mites or thrips you seem to have there.
Best practice is to establish an IPM (integrated pest management ) procedure where you are spraying the plant at least once a week. Best to do 2x.
doing this across your whole garden will prevent infestation in the future.

once you have a pesticide product, spray 3x in one week to knockdown the population and then start your IPM routine.
Never spray in direct light.

ps- this applies to indoor gardening as well.
