Iwan. AB pests/diseases?

I found these marks on my AB, I think the black spot is sunburn, but as for the pitted ones, I thought "Oh s**t spider mites again?" and when I swiped it with wet tissue, I found nothing... but could it be something else other than the red spider mite?

The first and third photos appear to be random insect damage that is now over, so is more of an aesthetic issue than harmful to the plant.

The second and fourth pictures sure look like mite damage to me, and there are others besides just the red spider variety.

That last shot doesn't look like sunburn. Sunburn is the immediate death of cells due to overheating, so only occurs where there has been direct exposure to too much sun, so does not spread, but leaves a dry, parchment-like area on the leaf. That looks like a bacterial or fungal infection following some other damage, so I'd recommend cutting off that part of the leaf close enough to the plant so there is no discoloration in the leaf interior. If the plant is exposed to a lot of moisture, you might consider dusting the would with cinnamon powder to dry it up and prevent fungal attack.

Just to be on the safe side, I've snipped off the black part, and dusted cinnamon on the wound. Swiped the mite damage parts with Listerine, might use isopropyl alcohol once I can get it.

Thanks for the info Ray!
