Hey Bulls,
Right now I am using the General Hydroponics 3 part system (Micro, Grow, Bloom). I have some Advanced nutrients b52 and Iguana Juice Bloom.
One thing we need to keep in mind is nutrients vary over here compared to what you guys use over there. Not saying you don't use it, but I have seen your side of the world use other products vs North America products. This could be the only challenge, but again I am not saying this is the case here. So let me know :)
As for the EC Reader, I have a chart that breaks down EC to PPM. So no worries about that. Once I know the EC we are working with I will know the exact PPM that is required.
