What's the best way to fix a cal/mag deficiency in the middle of flowering for coco, without providing any extra nitrogen to the plant? Any experience?
I use Cal-Mag Plus in veg, but my base nutrients have plenty of nitrogen in them and I don't know if it's fine to add Cal-Mag to my feeding schedule in flowering.
How much Cal-Mag per gallon will be enough to fix a cal/mag def?
General organics has Camg+ 0.0.0, just water this in separate from your other nutrients and it should help. Future advice since your in coco you should always be adding additional Calmg and don't rely whats its you base nutrient especially in coco.
