I agree with Elaine, writing a booklet is a lot of work especially when updated information is available for free. I belong to the Garden Writers Association and can tell you that the professional writing experts feel the same way. It is just not worth it. However, sharing info like the folks do here is another, and very valuable, story.
My personal bias against Miracle Gro is that with herbaceous plants it seems to push top growth and flowering at the expense of good root growth. Obviously this is a different application than with orchids where you are looking for foliar growth and roots may be secondary. For plants like annuals MG is tops.
