Water Hardness Gives little room for nutes, replacing it with distilled = way more nutes?

My tap water is at 700EC (very hard), and I add nutes normally until around 1000EC, which gives little room for nutes, if I replace with distilled water, can I go up to 1000EC with it ? (gonna be a LOT more nutes).

My tap water is around 300-350ppm or 0.6-0.7EC I will mix my feeds up in it and have no ill effects. its on the lower end of hard water if you place it on a scale vs others. Hardness of the water is not judged by its PPM count but more so how much of the mineral content is calcium and magnesium. Other things can influence the EC of water but not make it hard. Distilled waster will have many more available nutirents vs tap water when both are at a EC of 1.0 or 500PPM if using the 500 scale. If tap is .7 that only leave .3 of fertilizer to make 1.0EC but 1.0EC in distilled "0.0" is 3.333 times stronger as theirs no base charge like in tap water "0.7", and with liquid fertilizers they are totally available to the plants where tap water has compounds that will not affect the plants right away as they need to be broken down first. So you could run the risk of overfeeding in that setting. Best Of Luck!

Hola si estamos hablando de ppm llebarlos a 1000 en etapa vegetativa seria mucho. En etapa vegetativa mantengo los pmm entre 500 y 700 que sería 1ec y 1.4ec. También ten en cuenta la carga de nutrientes que tiene tu sustrato Tu agua es muy dura y no permite agregar nutrientes a tu dieta. Mi agua tiene 500ppm es dura también. Compro agua filtrada 1 vez por semana y riego con la misma que tiene 200ppm y me permite agregar más nutrientes. En floración tienes más margen por que puedes llevar tu ec hasta 2.2ec= 1100ppm suerte.

assuming 0.7EC? that'd be about 350ppm. that is hard but should not be a problem. I have realtively the same hardness. not a problem in 4 or 5 years, whatever it has been. i started using soft water last winter with no issues (logistics forced the decision, but no ill effects, think it may hav even helped with antifungal properties of plants, but not certain) with a soilless substrate you can easily start at 1.3-1.5 EC. heck even a seedling won't burn at that concentration, but is better to start at a reduced strength the first week in my experience, and even when ramping up there's a bit of lag between what you feed and what the substrate is. Be religious with that 10% runoff waste water and substrate will not be the cause of any "buildup" unless you upped the concentration yourself ... can still happen in the plant of course. they cannot excrete waste. so any mineral you feed at a faster rate over time than it can use will cause a toxicity in plant. all about finding that right rate feeding... will vary by local environmental factors. growdiaries.com/static/img/04a614e499ea563bf72eb4fffeda9585.jpg i see now... it's just shifting decimal 3 spots, so easy translation. definitely stick to EC... as you can see these pens calculate ppm vastly differently due to manufacturer and nothing to do with reality. all are guesstimates on ppm - the cheap ec/ppm meters.
