Too much nitrogen. Excessive mineral salts in your growing media. Ease up on the feeding would be my advice. Go to half strength.

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.
