Nutrients.. EC, TDS, mS... Questions..

I'm seeing these conversions.. .5 or .7 for TDS

I have a hanna tester that reads in mS ... How do I know which conversion to do??? Do I want TDS .5 or TDS .7????

Or what is a good reading in mS off my meter?

here's a link

It depends on who you're talking to. If you're just using it to check things out then note your numbers and work from there. It really doesn't matter unless you're trying to follow someones advice specifically. If that is the case you have to ask them what conversion they are using.
