Well aware of the search feature my friend, I just found conflicting answers to my questions....thus the new thread.

I've read that some use MG and that some avoiding it all together. I have a nursury near by, I was hoping to get some nutes today. If not, I have to order them....and I'd rather not order. Can anything be used from Home Depot?? Is MG ok? If so, what kind??

Thanks.
