RO water regimen

I’ve just installed an RO system and I’m wondering about the modifications this will require to my watering regimen. My system will provide for inputs, veg formula, flour, formula, watering formula, and pure RO water. The watering formula will contain B1 vitamins and hormones and I assume that this should include calmag. Do I have to worry about build up of calcium or magnesium? When I water with RO water should I include Cal mag?

@thynk3r it depends on what type of watering system you have. Are you doing rdwc?
