Just got my res change done and a clean up done
@Mikis even canna mono calcium has nitrogen in it. Any calmag suppliment that uses calcium nitrate as its Ca source will have N
Some use calcium chloride as the Ca source which i read works better in foliar feeds.
But most people want to avoid Cl as only a tiny amount is needed and theres more than enough in most tap water.
Need feckin walter white to make a good nutrient schedule.....
