Any suggestions on what I have here. I got this from my daughter as a clone, but I have been fighting these brown spots for a long time now.

They look wet to me. Are the trays under your pots holding water?

No, I have been top feeding, this plant in particular is not sitting on the bottom of the try. I have it on a rack to keep it out of the water runoff. I have been letting the plants dry back before watering again.

In my experience that looks like a root issue. You might allow the soil to dry out just short of wilting before watering again.

I would consider try watering less, and keep the soil moist without runoff. It could be stressed from going from wet to dry.

I agree looks like over watering

So I went on vactions a few months ago. I had someone watering for me. I came back and they were yellow similar to that. What is your humidity? Mine had a little to do with that, but mostly because they were under fed.
I bet if you start feeding some calcium and alternate a fed that has some nitrogen, the plant will start to green back up. I run ec at 1.5 to 1.8. Which is about 500 ppm low end and 850 high end. So, repeat alternating them until you see them green up. I don’t think it’s a ph issue. That tends to look a lot different. This process could take a couple weeks.
The soil does not appear to be over watered.
Something I make sure to do is visit the plants everyday at least. I swear they feed off your energy. Anytime I go away for short time my plants always let me know they’re not happy about it.
On this first photo the plant in the back corner I followed the process to regain it’s color.
