Regards the EC generally seedlings like 0.6 to 0.8 (will vary strain to strain etc). This includes the EC of plain tapwater. My water is 0.4 from the tap so I would add another 0.2 to 0.4 of feed to bring the total up to 0.6 to 0.8.
If your water is below 0.2 from the tap add calmag to bring it up to 0.4 first then add your nutrients upto 0.6 - 0.8.
Measure your water straight from the tap then add your nutrients accordingly to bring it to range.
