Fertigation, EC Creep & pH 5.8–6.2
Shot size and frequency, the 10–20% runoff rule, why EC creep (not waterlogging) is coco's real failure mode, and holding pH in the 5.8–6.2 band.

In coco, the enemy is salt — not water
The most damaging myth in coco is "overwatering." Coco holds air and water simultaneously (RHP-certified blends target roughly 70–75% water / 20–30% air by volume at field capacity), so a well-managed coco pot is structurally hard to overwater. The real failure mode is EC creep: salts concentrating in the root zone. Every problem you'll blame on water is usually salt.
