It is going to depend a lot on your water. My well water comes out at 11 ppm and PH5 so it is more or less acidic RO. I find that I need to add quite a lot of Calcium Nitrate to keep plants happy. So much so that I essentially never use the Maxigro any more. If I did, I'd end up with way too much Nitrogen so I end up using maxibloom with calcium nitrate in a 4:3 ratio for veg. I switch to Calcium nitrate and Koolbloom for bloom and back off on the ratio as warranted. As with anything, you need to see what your plants like and adjust but I find that with Calcium Nitrate as the main nitrogen source, the tolerance for fairly high ppm is common.
Ha! Thats funny... If you look at the "Full Analysis" tab on their page they list:I use Maxigro right now with tap water at 150-170 ppm. It does have copper, iron, manganese, borate and zinc.
Ha! Thats funny... If you look at the "Full Analysis" tab on their page they list:
But if you look at their actual ingredient list it is:
- Total Nitrogen (N)10.0%
- 1.5% Ammoniacal Nitrogen (N)
- 8.5% Nitrate Nitrogen (N)
- Available Phosphate (P2O5)5.0%
- Soluble Potash (K2O)14.0%
- Calcium (Ca)6.0%
- Magnesium (Mg)2.0%
- 2.0% Water Soluble Magnesium (Mg)
- Sulfur (S)3.0%
- 3.0% Combined Sulfur (S)
- Iron (Fe)0.12%
- 0.12% Chelated Iron (Fe)
- Manganese (Mn)0.05%
- 0.05% Chelated Manganese (Mn)
Ammonium Molybdate, Ammonium Nitrate, Calcium Nitrate, Calcium Sulfate, Copper Sulfate, Iron DTPA, Magnesium Sulfate, Manganese EDTA, Potassium Borate, Potassium Nitrate, Potassium Phosphate and Zinc Sulfate
I wonder why they don't include that. Or at least just have a one liner about trace micronutrients.
Anyway, I'm glad I looked for an alternative anyway since the price difference is pretty solid. Maxibloom is $5.55 a pound and masterblend is $2.60.
