kinda weird that i have to put alot of this stuff to lower the ph values
Does what it's supposed to
Only used 1 tsp/gal on 2 waterings.
Seem to really help! Not sure tho if I should get some cal-mag without Nitrogen or if that matters at all???
Honestly didnt use enough of it to see an effect good or bad. Only had a little left
Try it ir works wonders with my super soil and ACTs
One of the best dry admendments money can buy and it last forever... A little goes along way
Excellent addition to help synthesis those nutes the plant needs.
I don't really use CalMag from Black Macic, they just came up on the list. But the plants did seem to like CalMag added to their routine
Didn't really use Black Magic Cal-Mag. But I do think Cal-Mag is helpful
