Bloom City Professional Grade Ultra Pure Cal-Mag Growing Supplement Gallon (128 oz)

Bloom City Professional Grade Ultra Pure Cal-Mag Growing Supplement Gallon (128 oz)

Q: Is there nitrogen in this? It would be helpful for the seller to post the bottle back side label.

Hey there, good idea on posting the labels, adding that to my to-do list! To answer your question, yes there is Nitrogen. Here is the guaranteed analysis of nutrient content on our Cal-Mag. Total Nitrogen 2%, 2% Nitrate Nitrogen, Calcium 2%, Magnesium 0.6%, Boron .002%, Copper .003%, iron .004%, Manganese .004%, Zinc .004%. Derived from: Calcium Nitrate, Magnesium Nitrate, Boric Acid, Copper Sulfate, Ferric Sulfate, Manganese Sulfate, Zinc Sulfate. Hope that helps! James - Bloom City Crew

Q: Site says it is compatible with all growth mediums, but bottle says for hydroponic use ONLY. Which is it?

That terminology on the bottle is unfortunately a labeling requirement placed on us by regulators. It is compatible with all growing mediums, including soil, cocoa coir, peat, hydroponic systems, etc. Thanks, James - Bloom City Crew

Q: Can this be mixed with epsom salt for additional magnesium as a foliar spray or added as a root drench?

Hi, Great question. It can be added to epsom salt in a water solution, however we suggest you try this Cal-Mag first on the plants - its probably more than enough magnesium. We use highly bio-available mineral forms and add organic acids to the product to increase uptake. Its also great as both a foliar spray and a root drench! Let us know how the plants grow!

Q: What would be the salt in ppm per dose added to ro or distilled water?

Hi, thanks for the question! The PPM added would be about 120 for the low dose of 2ml per gallon, and 240 for the high dose of 4ml per gallon. Let us know if you have any other questions! James - Bloom City Crew
