  1. Tap water is probably better for beginners. Will also save some money on that cal-mag. Can get away with epsom salt unless you grow in coco or hydroponic. But I get your point. When I started growing I used RO water and got calcium deficiency (50% soil/50% coco, indoor that was)

  2. Can anyone answer my question?? How do I adjust the ph level in plain Ro water when watering fresh seedlings in soil?? Blue lab ph pens will not read correct ph level in plain ro water with ph solution.
