it won't hurt the plant, BUT Miracle gro is a cheap fertilizer...it doesn't have the variety or the amount of nutrients as higher grade fertilizers do.... so often people compensate by adding MORE fertilizer.. that's bad..

Quality over quantity.. in many aspects.

basically, you can use Miracle Gro.. but it won't do much... if anything... you'd be better to not use fertilizer at all.
