I used cal-mag for magnesium? Is this wrong? :S

I will change the water as planned tomorrow, and try to be more exact with the amount of nutes. I am using GH Flora series and Sensi Cal Mag Xtra from Advanced Nutrients. How much should I use? Last timed I changed the water, I used half the amount (3.5ml/10l) of the GH schedule.

I had magnesium in about two days ago. I used cal-mag and epsom. The good green color is coming back slowly, but it seems like the burning wont stop. Are there still to much nutrients in the water? My sprinklers are spraying directly at the roots? Is this right or should only the bottom roots...

Today I used cal-mag at half-strength. Is this enough or should i use more? Should I also supplement with epson or should I only use epson? Can too much iron, manganese or calsium create any sort of lock-out? I will buy epson tomorrow. Since my plants are in bad shape, can I maybe shorten...

Anybody?

I bought a new ph- and ec-meters. Separate. So they have been used for about 3 weeks. Calibrated them once a week. No new batteries yet. How often should i change them? Start with root zone how they look? What do you mean? How the roots are looking? If so, they are just looking fine. Crazy...

I do have some problems with my plant. Today the EC-meter was showing 0.86 in the reservoir, and 0.6 by the roots. The ph was lying at 6.2. I changed the water in the system with a ph of 5.3 and Ec at a little less than 0.5. I use General hydroponics nutrients and Canna ph down. The system is...
