Hi Mr Champ,

Good to hear you are gettng some meters.......sorry that I don't know the answer about your other meter. What brand are you getiing? Make sure you understand the difference between conversion at 500 as opposed to ec conversion at 700 and whichever conversion you are going to be working with.

Yes, I generally mix things up in a seperate bucket, ph everything last, and then add the solution to the regular res. I stick with pretty simple; add some then check the number, then add more. It's much easier than you think to overdo some nutes and ruin your wanted ratios.......I've had to stop and dump an incorrect mixture more than once.
