Mycos

i have a question about mycos. If they are used on a heathy root base plant, after they establish themselves, what happens to them if they get over fertilized. If a plant is showing n tox will flushing help? Do the mycos die? Does the plant continue taking in n from the mycos?

I know only because I've done it. If you give a fungal dominated root ball something it doesn't like (let's say it is a liquid bloom booster high in P and K like 5-20-30) it will not kill the fungi but it will upset them. In turn the fungi will stop absorbing all nutrients altogether until "normal" conditions return. It is just like swinging the ph out of whack.
Fungi doesn't know what to do with soluble compounds that have NPK values higher than 5. They are not evolved to absorb anything like this so they just shut down. Some dry amendments have much higher NPK values than 5 but since these need to be broken down by microbes in order to be absorbed by the fungi they are released slowly. I hate to use the term flushing but giving plain old water is the only solution if the fungi is upset. The good news is it can recover in a short time; a matter of weeks.

I'm seeing the claw and foliage is crip feeling. Still green but clawing. I've transplanted into larger containers and the roots on the outer sides are white and healthy looking I can see root hairs and as far as I can tell the root system seems ok. My water does have chlorine in it. It's city water. I did a flush actually a heavy watering in after transplant so I'll let it dry out and see.

Chlorinated water won't effect mycelium at the amount chlorine used typically. Chlorinated water is actually advised to use in birthing mycelium cakes (brf tek) since it helps fight off bacteria
