Once again organix thanks for your help.
The water is ph balanced tap water at 6.05, nutes are at 30% of full recommended strength. Water is hard.

What is the EC before adding nutes?

Errrrr, I didn't check :banghead:
I will go and knock some up know.

Right with ph balanced at 6.06 the reading on my EC meter is 0.47
Unbalanced tap water has a ph of 7.7 and a reading of 0.51

Seems ok yeah. But I don't get how your EC is lower after adding ph down.

I added Ph down measured the Ph and then the EC. After that I just measured the ph and ec in a bog standard tap water sample.
Cheers for your help organix

that level sounds OK. I start seedlings with plain water for about a week, then switch to 1/4 strength nutes.
