WTF is Going on
ojetepelonanswered grow question 3 years ago
as my mates said:
1) Too much build up of fungi in the top of the soil (root problems)
2) Deficiency (K)
Buy trichodermas to control the pathogen fungi or use diatomea earth
Use a proper nute schedule
Wait till the soil dry 2cm at least before you water them again.

I see several deficiency signs. So my money is on your soil ph is likely out of range and your experiencing lock out

It looks to me like nutrient burning from way too much nitrogen.
Possibly fungal troubles too, from too much humidity.

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!Leaves. Edges burnt

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.Leaves. Edges burnt
