Canna coco coir Mold/??

A mycillium network can help with nutrient uptake amongst other things bjt I'm not sure if it's supposed to look this fluffy. It should look more like a feathery root system. Looks more like actual mould!! Good luck!!

Eso son hongos beneficiosos, vida para tus plantas. Lo malo si es de color verde, ahí estás jodido. Pero blanco quiere decir que ahí hay microvida que ayudará a tu planta. No te preocupes

you asked this same question last week. I will say the same thing. Looks more like mycorhize to me. But could be wrong. Molds tend to smell sour, mycorhize tends to smell earthy and like mushrooms. If you touch it and its powdery on your hands, then I'd say its mold. If it just compacts into the medium and does not come off I'd say its mycorhize, not a fool proof test just a basic one. are any of your nutrients your adding have any mycorhize? eg. voodoo juice, Best to link your diary that this is about. Good Luck!
