I added some cal/mag a few days ago, and it seems like she is slowly improving. I dont really have any hope left for this plant, but it has been a really good learning experience. Coco is more difficult than soil, but I feel that I'm starting to get a grasp on it, and so far it looks very promising. My other plant is in week two of flower in coco and doing amazingly. This is because I was using differnet nutrients that had calcium and magnesium in them.
Gotta use cal/mag all the time if your nutes dont have it in coco, did not know that.
