I used MG alot when i first started and it never killed one plant. Dont know where you get your info from but id start getting it from a more reliable source.

As for yellowing leaves at the bottom, its pretty normal especially during flower. If you are getting spotting on higher leaves it could be due to ph issues. Im just guessing here so if you want a more accurate answer the best thing you could do is fill out a trouble shooting form and fill out the best you can.
