I am getting mixed feedback on what the issue is with this plant and I am not sure which direction to go. It should have about 3 weeks before harvest. I started to notice browning, the leaves seem brittle and it’s getting worse each day. At last watering, the runoff was 884 ppm and 5.2 ph. All of my other plants look fine with runoff from 775-1120 and ph 5.9. Is this from too many nutrients? Ph being too low? Calcium deficiency?
