From what I understand fungi are real sensitive to synthetic nutrients, especially ones high in Phosphorous.
Here's a blurb...
"High rates of fertilizers, especially phosphorus, inhibit the formation of mycorrhizae; organic forms of fertilizers seems to have less inhibitory effect on mycorrhizae than inorganic, soluble fertilizers."

What I would do is add a few things to the soil that you already use. Worm castings, kelp meal, neem seed meal, and crab shell meal. Mix that up in your soil, wet it down with a compost tea, and let it sit for a few weeks. Plant your clones in there, and then use water only through veg. Once you hit flower, you can start introducing your inorganic nutrients as needed.
You will have a thriving colony of beneficial microbes, and your miccorhyzal network will be established. The plant will benefit from the organic inputs (pest resistance) and the symbiotic relationship with the microbes. Best of both worlds kinda thing without diving head first in to it.
