Been fighting yellow and brown leaves

So for a week or two now I’ve been fighting yellow and brown spots on one of my plants. I must be misdiagnosing it and just all around making things worse. I know brown tips are over fertilizing. But what’s causing these other spots? The last two pics (with the more yellow leaves) were taken a couple days ago. First two just now. Any advise would be a huge help I’m kind of at a loss here. Thanks

If your spraying them with something where they are still wet when the sun is out I would stop doing that. That will cause the leaves to get burnt by the sun which can look a lot like what your showing.

The upper growth doesn't look as effected?

That was end of day and no direct sunlight. No problems at all with new growth that I’ve seen. mostly lower on the plant. No idea what’s causing it

Water droplets don't form lenses which concentrate light to burn leaves.

That myth should die sooner rather than later; it's easy to disprove - just spray an outdoor plant on a sunny day.

your plants look underfed.
