Have you checked the underside of the leaves for bugs? Looks like bug damage.

Yes, ive used a magnifying glass to look under the leaves and they are clean, no bugs crawling…
Should be 5.8 - 6.2 range for coco @D1hunned
Much different than a soil grow.
Didn’t happen to get the leaves wet during your flush did you.

@D1hunned First thing to do is adjust your PH to 5.8 when feeding

I agree, start setting ph to 5.8. Any time i have flushed in coco have immediately followed with reset nutrients. The cation exchange capacity of coco can make it complicated if allowed to lose it’s buffer.
