If you were like me...mg was unsuccessful for two reasons.

1st...it was the most handy fert around for the ignorant new grower to grab out of the garage. I used their liquid variety btw.

2nd...As a new grower...who hadnt yet found all the gobs of info available in and around here...soon showed me that ultimately I had been burning the piss out of the things.

No doubt mg being far from the best blend of nutrients (chemical by product neon fertz are best avoided imho), combined with me seeing a 3 week old plant suffering some sort of ailment, yea...right at the first signs of over ferting...I did the ''omgosh! something is wrong...I better give it more nutrients asap!'' blunder of blunders, is why mg was set-up for failure from the start.
