When I look at your leaf tips... they're curling and turning yellow/brown. That's a sign of nute burn what means your soil has a way too much nutrients and because of that your plants can't take anymore so it shows other defencies. They're totally stressed! I would not use any fertilizer at this time only clean water until they have recovered. Good Luck!

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.
