What is wrong with this plant? I am growing organic and using no synthetic nutrients. Watering with ph around 6.5-7 in coco coir. Lower leaves are starting to yellow and tips browning and curling upward.

Coco is classed as a Hydro medium so the ph range is lower, 5.5 to 6.5 with the sweet spot around 5.8-6.2 hope this helps.

Over fed.
5.8 pH for coco coir is the accepted standard.
Incorrect pH can cause issues with nutrient absorbtion.
I would also suggest watering the entire pot until you get a decent run-off and not just a small amount next to the stem.
It is almost impossible to over water in coco.
