I ran into a Cal-Mag deficiency due to an excess in Potassium. In trying to circumvent the problem with the Calcium deficiency, I tried Foliar spraying the leaves with Cal-Mag in attempt to deliver the calcium via the leaves but, had no luck whatsoever.

Does anyone know the correct procedure to effectively deliver the Calcium nutrient via the leaves?

Mix according to recommendations on the bottle and pH to 5.8. If you have and TDS/EC meter you can dilute it to about 1.0 EC. I use dish soap or polysorbate20/tween20 in my foliar sprays to make them wetter and more effective. Good luck!
