Well they always need water.My plants stopped feeding nutrients doi give them water
Precisely. We are pretty good at getting by with minimal input but we aren't Helen Keller.Way more details are needed. What have you been feeding them, at what dosage, how often, and the type of medium you are growing in would be a good start.
If you want people to help then you need to explain the dosage. I don’t grow in coco, so I won’t be of much help, but even those who do can’t help you without knowing if you’ve been over feeding all along.I'm using shogun nutrients and coco media I'm on week 8 of flowering
