I don't understand the question. All plants need micro nutrients, even soil grown plants need micro nutrients. But with soil grown plants the micro nutrients aren't normally added as a fertilizer because they generally get what they need from the soil (as well as some from the water itself, unless you use distilled water to water your plants). Their called "micro" nutrients because they are required by plants in much smaller quantity than the other elements. Therefore are rarely added to fertilizers intended for soil. That's the basic difference between regular fertilizers and hydroponic fertilizers in a nutshell.

So if the question is will plants grow without micro nutrients (soil or hydroponics)? The best answer I can give is yes, but not healthy at all. If you took the micro nutrients out of the soil, you would wind up with more or less the same result as growing hydroponically without micro nutrients (assuming that all the other elements in the nutrients as well as the growing conditions are the same).
