Last grow i didn't use any calmag at all and I didn't see any calcium or mag deficiencies, i water with tap water if that helps. I was thinking about getting some calmag because i hear its such an important part, is it always necessary? and if so how often? Also, what would be a good brand of calmag? i prefer dry nutes, i use maxigrow and maxibloom from general hydroponics
