Yea it doesn't look the healthiest .Give more info about grow. Tbh that plant doesn’t look very healthy
I'm growing out of soil , biobizz all mix and I'm getting a tonne of run off, atm I'm watering every 3 - 4 days about 2 litres and collecting at least 30-40%If you're in coco, it looks like you're doing what I call "lazy watering", and probably not watering often enough with runoff, so the coco gets "built up" with salts.
I recently had this problem because I was only wetting my coco and not getting runoff consistently. I'm back to a religious watering schedule and runoff collection and my plants have EXPLODED.
