Too soon for leaves to be turning brown and curling!
The auto widow circular leaves are curling at the tips and the tips are turning brown, and one of the pineapple kush auto circular leaves is not only brown at the tip but looks like about a third of it on the end is gone. See photos. What might be going on and what can I do?

Is this nute burn or other deficiency? I did increase the feeding a bit. But also just came out of a calcium deficiency. Not sure if the one with brown edges was from before tho, I forgot to clip a couple leaves with brown spots

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!
