Never understood soil and coco mixes, both mediums require totally different watering regime. Looks like you feed wrong, as Ez said both parts used from begging just in right proportions. Ph could be off too, many things can lead to such state. One thing 4sure 2.5 ml/l calmag is insane dose. Its not magic stick, its food, should never go higher than 1ml/l in 90% of brands.
