No, you don't need to foliar feed these micronutrients. Chelated micronutrients were invented because many of these nutrients only work within a very limited pH range of soil or soilless medium. Chelation protects the nutrients against pH damage and lets them be available to the plants across a broader range of pH.
The more important thing to me is organic (for example, manure) vs synthetic (chemically manufactured nitrogen source). Now, discussing this is like talking about religion or politics - people tend to have strong opinions. This is my take on it, after decades of growing happy, healthy plants. You can take it or leave it.
I go with synthetic fertilizers (good old Miracle Grow, at half the recommended rate, every time I water) for all my peat-based potted plants. Organic fertilizers need to be broken down by soil microbes before becoming available to plants. This takes time, months to years, AND if you are using a soilless potting medium like I do, it is hard to get flourishing microbial life to begin with.
However, in my garden, in the ground, with dirt and worms and things, where I can plan a year ahead, I prefer organic fertilizers. I still tend to get pre-mixed stuff (I like Dr. Earth) rather than try to balance manure, compost, blood meal, guano, bone meal, etc into something my plants need. I only add a single product if I can see a difficiency. There are probably recipes for complete organic fertilizers, but it can take months to see results from what you add (the stuff has to travel through the gut of microbes first...), so it is almost impossible to tell which thing you added had what effect.
Did that help, or confuse you more?
