Question Question about EC

Hey guys. I am hoping someone can give me just a little assistance in deciphering an article I read in a forum here on Percy's about EC. Ok... so first of all my substrate is soil/coco/peat/perlite mix. Secondly, I am using all biobizz nutrients. Now one issue is that the thread does not actually discuss EC for soil. It goes over hydro and coco. Does this mean that I do not need to worry about my EC when using a primarily soil substrate? Additionally, I am still not sure what I am looking for in a range as far as optimal EC levels in my water. My tap water here has an EC between 600-700 us/cm2, the water that I had been using previously has an EC between 500-600. I am not sure if this is an acceptable level or if it is too hard or soft? Also... with that in mind, what is the process of correcting water with a high EC or is there one? I realize that some people do RO for softer water and lower EC. So does anyone have any insight or a little clarification on this for me?? MUCH APPRECIATED FAM!!

@wanderluster hi mate

so when the food runs low (or just before it does) in soil for veg plants I feed at 1.2 EC 

If using bottled feeds (inc bio bizz) for flower I start at 1.2 then this gradually rises through to 1.6 maybe 1.8 if a hungry plant..before being reduced back down towards the end and then plain water for let 2 weeks ish 

that’s if not amending soil before hand with extra (dry) nutrients 

biobizz instructions to be fair are pretty good so if followed accurately along with watching what your plants look like you should find it straight forward 

hope that helps a bit

Time to pop some more beans 😗

@chillbert Ok.. yes, that does make sense. I think I am starting to understand it a little better now. I have been watching my PH regularly and going low on the nutes as a rule so I think I am still falling the the safe zone. This latest grow is leaps and bounds ahead of my previous 2 just from lowering my nutes, specifically TOPMAX which definitely gave me some problems when I upped the dose towards the end of flowering. Burnt the shit out of my leaves... But I just wanted to make sure I was understanding the EC part of it all. Thanks, bro, for the good information!
