Spots on plants

These spots are on a couple leaves of my plants. What could this be? I feed them fox farm trio. Did one feeding week and a half ago. They are outside.

What is your PH levels?
soil? Coco? Or mixed ?
are you feeding cal mag ?

After zooming it I believed it to be an infestation, but the edges are even turning that color so I'm thinking it's something happening in your root zone. Like Captain said, check your pH. pH fluctuations can display some pretty odd symptoms

I’m using pot for pot superb soil with coco husk. It seemed to happen a day after I started to use Ph up and ph down. I put a lot of drops of both trying to get it around the 6.5 range. I went over and under a few times.
