Coco is NOT soil. It needs to be fertigated (fed with every watering), never dry out, and always have CalMag. This daily checklist keeps you on track.
โ ๏ธ COCO RULE #1: CalMag in EVERY watering. Coco naturally binds calcium and magnesium, stealing it from your plants. No exceptions.
๐ก Runoff EC climbing? Salts are building up. Do a "flush" feed at half-strength, extra volume until runoff EC drops. Then resume normal feeding.
โ ๏ธ Letting coco dry out causes massive pH and EC swings that shock roots. Unlike soil, coco should always be moist. If you're away for a day, water extra before leaving.
