*sorry for bad/blurry image's its the best I could do atm.
My rooted rooted off a while ago and recently starting growing back nice and white so I added some beneficial fungi (mycogrow
MycoGrow? For Vegetables--1 oz - Fungi.com ) about 1/16 of tsp in the hopes it would prevent future root rot 4 days latter they turned from very slight brown to that image.
Is that the beneficial fungi growth or root rot? Hit it with h2o2 and kill everything?
/edit did a water change roots don't look as bad as I though 99% sure it's the fungi.
