[tronic]

Hey fellow grows I'm a rookie grower an could use some help. My plant is in its 2nd week of flowering in coco and the edges of some of the leaves are curling up and some have what looks almost like nute burn. Just unsure what it is nute burn, mites, or something else. Thanks

russet... like the potato?

I myself am a rook so take this with a grain of salt but I would check your PH. What and how much are you feeding and watering? What are the temps like? We need more information before we can help.
