Black Magic

Does what it's supposed to

Only used 1 tsp/gal on 2 waterings.

Good

It works

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

Worked well with the problem I had, great stuff

It works magic!

just like any other calmag

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

Trying a new brand to me works as stated.

As advertised

kinda weird that i have to put alot of this stuff to lower the ph values

Good stuff as always

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

Did not use it.

Good stuff
