At the moment i am using tap water with an EC reading of .8 ph in the high 7. im not sure what other crap is in my tap water.
yesterday i purchased a 125L tank and its been out under my down pipe for 1 day and its half full already. the EC of the rain water is so low my blue lab truncheon does not read it.
my question is will canna A+B be enough to supplement the lack of other elements that the tap water has. if i remember correctly canna is based on soft water it may be ok ?. will i need to add cal/mag or other nutrients ? going to hydro store tomorrow if i need to pick anything else up.
