spots on leaves
Default spots on leaves

Some of my plants have always had spots on their leaves, which I attributed to my (formerly) poor treatment – maybe a minor fungal/bacterial infection that never spread further. But after reading the recent vendor reviews, I'm getting paranoid about viruses. I didn't know viruses could cause black spots – I only knew about color breaks in the petals and discoloration/ring patterns in the leaves. I've attached a couple pictures of my plants below. Can y'all tell me if my plans are fine? I've named the pictures to distinguish photos of different plants.

ps: the zygo definitely looks the worst but the last photo is of a healthy new growth on the same plant.

Zigos (among others) are prone to leaf spotting...air flow is the best preventive/remedy.
But in your case I would look also for mites.
