I agree with Jandey1 (what happened to Jandey?). I had the same issues before and its been spider mites. Since we have opposite seasons from you, it must be getting close to fall, you may want to cut the leaves and spray. Good Luck
Cheers

I don't know how much longer your growing season is, but I would treat them with pesticide on both leaf sides or a systemic, and move the plant to a shadier spot. Rain actually might be beneficial, but not buckets and buckets of rain!

I also agree that looks like mites, for sure. Jen, sometimes I don't see the red spots but little yellow spots that let me know the suckers (literally) are there, what are those?

Thrips will also do that.

Thank-you all. I've put on naturasoap so hopefully that will work, or I can try spinosad or spinetoram. I saw lil orangey dots moving around on the leaves.

Red spider mites... I would use Bayer 3 n 1 to take care of the problem or use a neem oil / alcohol/ Murphy's oil soap mix with warm water. If you want the recipe, I'll post. You need to treat again after two weeks to kill eggs.

Good luck!!
