Athosanswered grow question 7 years ago Try this for a water / feed schedule for coco, forget any half strength or half assed rule like that, get a TDS/EC meter an use that, take this as a guide.
Week 1: 0.6 EC (300 PPM) , focus on cal/mag (or similar).
Week 2: 0.8 to 1.0 EC (400 to 500 PPM).
Week 3 and rest of veg: 1.2 to 1.4 EC (600 to 700 PPM.
Flower: 1.4 to 1.8 EC (700 to 900 PPM)
I'm giving you ranges because different strains will like different nute strength, also different light setups will affect this also. Like the nutrient requirement for a micro grow is different from a plant under 1000W.
