Nutrient questions...CRF, micros, etc

I'm growing mostly dwarf conifers and some japanese maples in containers using gritty mix. I've been using Osmocote plus 15-9-12 applied once in the early spring. I sometimes shoot them with my liquid flower fertilizer as well, which i'm using Jack's general purpose 20-10-20 (analysis link) out of an injector.

Both of these supply at least some amount of micronutrients, just not sure if it is adequate. Would it be wise to add micromax to the containers, or am I getting enough from the osmocote?

Any information would be appreciated.

And a big thanks to this forum, especially Al, for introducing me to gritty mix. My plants love this fast-draining media. I will be trying the 5-1-1 for some plants this year as well.
