They can stretch if you let room conditions get away from you. Depends. I grow exclusively in coco coir (canna brick) in one to 3 gallon root pots or grow bags and feed ionic (or any other cheap one part base nute) grow and bloom at 550 to 850 ppm using the 500 conversion scale. I feed daily and multi daily feeds using a drain to waste drip manifold. I keep pH anywhere from 5.7 to 6.1. I sometimes use additives like b cuzz root and bloom stimulators, terpinator, silica, cal mag (rarely). I swear by doing a weekly foliar spraying in veg with nitrozime kelp and bioag ful power with a wetting agent (yucca). My starting tap water is 110 ppm of calcium and magnesium carbonate and has a pH of 7.6.
