I am going to address a concern recently pointed out to me. There is good evidence that once we enter bud and start feeding bud nutes, the mycos actually turn parasitic. IOW they no longer help our plants do anything, yet the plants continue to waste energy feeding them.
But remember, we do not use mycos in DWC for the symbiotic relationship. We do not hope to gain the extra feeding and soil exploration they are known for. We want simply to displace disease. This is a purpose that mycos continue to serve even if they turn parasitic. You can look at it as simply a trade off. Your plants send a little energy down to the fungi and in turn they keep slime away. Once we get to using very high levels of bud nutes, it's likely the that mycos completely die off anyway.
If you are too concerned you can simply sterilize your roots once you put the plants into bud, and reinoculate with tea. The mycos will not have enough time to develop a new colony before harvest, but the other beneficials will.
