Thrips?..... but NO other plant has any symptoms

So the plant with an issue is a plant I started from seed and all was well. My buddy dropped off 14 (and bringing more,) coco plants and they look fine while the plant I started beforehand looks like shit... thoughts?

if it was thrips, I’d just get some captain jacks (spinosad.) It worked last time. I don’t see anything on any of the other plants that seem to correlate. I bet a transplant would help some for sure, but there’s more to this.

sorry, can't tell from those pics.
need a macro shot of both sides of suspect leaves

Pics arent the best but i dont see any thrips damage.

Looks more like nute or ph issue at first look

No trips, dont se white spots on leaves

What are your watering habits?

How often are you feeding?

At what EC/ppm?

what pH?

No signs of thrip damage. I currently have thrips and they leave silvery looking areas on the leaves where they feed. Very shiny where it's fresh damage and the adults are visible by eye but easier to find with a big old magnifying glass. Random spots would indicate mites.

That looks more like burning of some kind with all the damage in a central area like a light was left jammed in the middle of the plant. Leaves away from that area seem fine tho a little droopy.

If it was a deficiency you'd be seeing all of the plant affected and it's just that one side so I doubt it's that.

My vote is for physical damage of some kind and possibly involving heat.

This is Thrips damage. You can even see one, little yellow Fucker. This is my plant, fought them for a couple months.

IMO you do not have thrips.

If you do get them, use predatory beneficial insects like Cucumeris.
