Switching from soil to coco coir — what changes?

Coco is hydro, not soil. Key differences: water more frequently (1-2x daily when mature), always add CalMag, pH to 5.5-6.2 (not 6.0-6.8), feed every watering (no plain water days), and never let coco dry out completely. Growth is faster than soil. Yields are typically 10-20% higher. Learning curve is moderate.
