Hey blades, I recently got myself some distilled water. I'm starting a hydro set up. I've heard that after water is run through a reverse osmosis filter, some minerals and/or micro-nutrients the plant needs are also filtered out. I've heard that cal/mag needs to be replenished after filtration. Which minerals/nutes do I need to supplement for? How will adding nutrients to my reservoir impact my ppm? What are optimal and recommended ppm levels for a hydro grow? Thanks!
