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!

watering is reactive... you react to the outcome. you are soilless so it's even simpler. fertilize every single irrigation around 1.3-1.5 EC. ratio/balance is obviously key, so you'll have to work that out over time.. observe and adjust. in coco, wait for top layer to start changing colors, and it's a good time to fertilize again. If the plant drinks fast, more frequent fertigation is possible and you do realize additional growth from that method. I'd suggest forming a good baseline doing it a safe and conservative way first, then you can more easily assess whether any risks of doing it are worth it or not. you need at least 33% loss of water weight before you fertigate again or you'll just drown the roots or increase risk of infecion in roots. i wouldn't do this early on in life. a larger more mature plant or as you go into bloom, sure. I'd rather i grow my roots early on in a way that makes them grow deep and aplenty. roots follow moisture in a reactive way. you get fewer superficial roots (at surface they become useless if exposed to light) by having a good wet-dry cycle. the top will always dry first. if you want to do multiple fertigations a day or water when the pot is only lost 33% of the water you previously gave (can feel the weight to judge), wait until the plant is a bit more mature or flip to bloom. growth is a curve. it's slow at first. these sort of things help, but not nearly as much later one. it's worth the small loss for improved root growth early.

Could be lockout, to help identify your deficiency issues I recommend reading this blog https://futureharvest.com/blogs/articles/how-to-identify-cannabis-nutrient-deficiencies?_pos=1&_sid=f81d0e725&_ss=r Because symptoms often progress even after applying a curative approach I'd just make sure you are following your nutrient schedule keeping EC around 1.2-1.5 or so and maybe go easy on the epsom salt. Often times its a good idea to flush the media of nutrients with alot of water and then just introduce calmag to your regular feeding schedule. Lockout can occur too when a plant's environment, watering regimen and temperatures are out of whack. Coco coir can be slow draining so make sure it dries out before each watering.
