If you use a fertilizer with Ca and Mg and correct your pH you probably will not need to supplement.

Are you suggesting the my TDS may still be a little but too low to provide the needed Ca and Mg, and I should suppliment with a little "pure water" fertilizer that contains these elements? Are you suggesting a mix of "pure water" fert. with the "tapwater" fert. that I have now and mixing that with my tapwater or are you suggesting a switch to 100% pure water fert. and mixing that with my tapwater?
Thanks!

Oh, PS - I'll check and adjust the pH. is pH 6.0 considered ideal?
