Hi guys, just wanted to ask about pepper plants, calcium and tap water. Will watering from time to time with tap water replenish the soil of things like calcium and other trace metals? I know that water evaporating from my aquarium causes some hard water stains over time so I'm guessing there is calcium in the water. The PH in my area is a bit high though... about 7.5-7.8 so I dont think watering very frequently is a good idea but once in a while for the minerals?
