| Re: flowering with a deficiency urgent!!!!!
the point of using calmag+ is that it replaces essentials removed by RO process. With softwater...more often than not; You don't need it, but it is good to have a liter around for deficiencies.
If you use a hardwater micro formula, then you might need calmag if you are bordering hard and soft water...because hardwater formulas are light in calcium, and magnesium...At least GH 3-part. Peace
Make sure not to use calmag with epsomsalts, also... |
