hi guys… how many ppm or ec you get your RO water to with CalMag? i cant remember where i learn that you need 250ppm of CalMag…i been doing that since i read…didnt have super great results just 1 time…i dont know if its from that or something else. Please let me know what ppm/EC you Feed
2.5-5ml of gh's (general hydroponics) cal mag/gallon of RO water here & 1 tblsp of GH ph down/5 gallons RO water FOR ME.
I use about 300 ppm in tap. 1 tsp/gallon, or 200 ppm calcinit and 100 ppm epsom. 1 tsp per gallon is a good average dose. Many of these old formulas were designed that way.
