I feed once a day. She has always had her leaves curled down, and I dont know why. What do you think it could be?

... any TDS/EC readings on the feeds? pH too, and both on run-off? How much run-off do you generate? ....Coco is not a forgiving medium,.... curling could be a few things, maybe a bit of N toxicity... coco breaths and drains well, so overwatering is less likely as a cause,...
