does anybody know wut powdery white spots underneath my rockwool be? its all around its roots
agreed i think alot of us see this, i know i have. I wouldnt worry until you have white spots all over your leafs.mycorrhizal fungi, they form a symbiotic relationship with the roots of the plant. this helps to increase the plants ability to attain more nutrients while allowing the fungi to live off the plant. to sum it up, it is a good thing.
