this is hilarious. i just got off the phone with fox farm to ask them what the difference is between the "peace of mind" line and the "happy frog" line of dry ferts because i couldn't tell based on the website, and another thread reminded me that i was curious.
she said, "absolutely nothing" i guess they changed the name to happy frog and put it in a plastic bag, but people complained because they thought the cardboard box that peace of mind comes in "displayed better on a shelf"...allrighty...
i have been using the peace of mind 5-5-5 all purpose. i first used it outside on my tomatoes and was blown away, so now i'm doing a run indoors on my cannabis. my tomatoes this year DESTROYED my buddy's miracle grow tomatoes and we both grew from the same pack of heirloom seeds. so far it's really doing a great job on my herb.
i can't say exactly what will happen with your particular setup and concoction since i used a different npk, but i bet you're going to get excellent results. it's a very high quality fert. i mixed mine into the soil before i transplanted and i figure i'll top dress every 30 days or so, depending on how she looks. no teas, no additional guanos, nothing. i just used gardner's gold potting soil and threw in some worm castings, perlite, lime, and a bit of "plant success granular" (whom i recently learned lost their "omri" rating but i'm gonna use the stuff anyway because i love it).
the japanese maple has a ratio that's more geared for flowering. i just went with the 5-5-5 because i plan on using ONLY that for the whole grow.
