For those of you that wonder why we keep a higher ph in our full nftg mixes, here is a word from Scott D Ostrander.
"Availability of the drivers (elements) that enter the plants. Most synthetics and hydroponic nutrients are nitrogen and potassium driven. And their forms of phosphates are all most available at a 5.6-6.2 range. So to best utilize those nutrients you drive them at a lower pH. Especially Nitrogen in a nitrate form, it drives in at 5.6-5.8. Hence Calcium nitrate and magnesium nitrate being their cure for mag deficiencies because they are driven in with a nitrate at a lower ph."
Sooo... Yeah. When we use nftg our calcium delivery system or drivers are most available between 6.2-6.6 range. Below 6.0 elements become less available.
