Robertsanswered grow question 4 months ago Okay, so I grow in coco, and have for years. This looks like you are not getting enough irrigation, and your ph is likely out of line due to the build up of salts from feedings. Coco should be ph 5.8 in and out in run off which is very important. Coco should always be kept wet. It's Hydro in a potter. But never left in run off. Start with a 5.8 ph water test till you get run off, and test run off ph and tds. Coco grows are nothing like soil grows. Happy to help. Feel free to PM me. 👍🏻
