splotchy leaves

fzyflwrchldAugust 17, 2014

I tried to Google what it might be but keywords "splotchy leaves" only got me cannabis growing websites. I'm on the second floor with a north facing balcony in D.C./VA. It's affecting my zinnias, sweet mint, and spinach. I have other mint plants but they don't look affected, none of my other plants look affected either (rosemary, daisy, strawberry, sunflower, lavender). It had affected my marigolds and nasturtium but then it went away.

Have you checked for spider mites? They would be on the undersides of your leaves. That looks similar to mite damage that I've seen on some of my plants.

Yup, spider mites, you were right. Um, now what?

I wrote a long answer to your question about what to do but I guess it got lost in cyberspace. The simplest way to deal with spider mites is to wash them off with a stream of water. If you can mist the plants daily, that might help. They really prefer dry areas, I've been told.

Ok thanks! I'll see if it helps. Do you know of the leaves recover from the splotchiness? I read online to use isopropyl alcohol to wipe the bottom of the leaves so I did that, hard to tell if they've come back or not though.
