Well they don't look on death's door like birdboy's stuff does to me (yikes!) but I have a feeling the root of his problem is most likely ph lockout......coco is notorious for needing it's own ph and unfortunately I don't know what that is. It's also known for needing (or not needing.....I can't remember which) extra calcium and/or magnesium. I think that's why they make special nutes just for coco growing.

Who knows the proper ph to water in coco, can anyone help?
