@HubbaBubba, bro, i am always pre aerating tap water separately at least for 24 hours before use, to make all chlorine go out and only then i use it. And you know, my plant absolutely loves it, no CalMag problems ever appears, i even do not have Cal supplement and Mg is used only for daily foliar feed in veg (now foliar feed will be totally different, but i will tell about it in details, when time comes, still in some research). At the winter it will be (it's always like that) up to 500ppm
Tried rain water, bottled water, well water, ground water (from the spring), melted snow water, my plants liked my tap water most. I do not have RO filter, so can't say anything about that, maybe it is good too, but after so many tries and still best results with tap water i have left this question alone for unlimited time. Tried to ozonate tap water, even ppms slightly dropped, but plant did not like it, so im not doing that again.
Theory is like this: tap water contains up to 1/3 of all needed elements, and if you could add extra elements just in needed proportions - tap water fits perfectly for growing. This is said by some nutes makers, there are special nutes for hard (tap) water, i'm using exactly it (Cellmax hard water line). My plants are happy, i'm happy.
If i make ice cubes - they are clear, maybe some of visible shit is on the bottom, but not much (surely it is there). If i freeze water in bottle - ice is forming from clean water and all chemicals are freezed last. I could freeze bottle till it is let's say for a half freezed, then take out the ice, melt it and use, and other part with concentrated elements i could throw away, but this is too much hassle and im not doing it. Main thing my plants are happy and im too lazy for it
Taste and chewiness? Maybe, to think logically - it should have some impact on that. But you know, hydro buds are already not so tasty as bio buds, so it is hard to get if there is any taste from tap or not. Im smoking my buds and i regret about it sometimes (bio buds are much much tastier), but hydro is only way i could go (my fucked up health), so i am satisfied just with what i have
Main thing cannabis does what i need and lets me live normal life, i could say simply lets me live
Adding to that info, just photo update of day 3. Plant seems to be healthy, roots still did not find it's way to nutes (there are some clay pebbles in it's way), but i know that they will and i want them to do it for themselves, i always do that
