[/quote] Doesn't look like a big deal. If it spreads to other leaves, then he should worry. Tell him to keep an eye out for any other problems, and to focus on new growth and it's overall health.
Unless he is using hydroponics some calcium is going to be locked out at 6ph. It should bounce around 6.5 - 7. Beginning 3rd grow(Apprentice) - BC Big Bud
That may be too high you should check I though coco was around 5.8 also coco has nothing in it so he most likely has a calcium defficiency. Soil at least usually comes with enough to keep em happy but if I'm correct coco has Absolutly nothing in it. It just holds the roots and the watering you do gives it everything the plant needs but check that I may be wrong.

Well I know I use fertigation which coco is the same thing. I use a soulless medium. Promix and all the food goes in with me watering it. And 5.8 is perfect for mine. Coco hand watered would also be fertigation. Basically hand watered hydroponics.
