Hi everyone. Me need help. I've been growing for a few months now, so far so good, until now! I'm growing white Russian, its been in veg for 4 weeks now and has developed a rusty colour on the leaves in between the veins. This starts as milky white spots that develop into rusty spots that then spread across the leaf. This is only happening in the middle to older aged leaves. Plenty of new growth coming through quite happily. I have included pictures for diagnosis. I'm growing in rock wool slab in an NFT set-up using canna aqua. Currently veging under one 400w grolux. Nutrient levels and ph are spot on. Air is free flowing, not being forced in or out as of yet. I've had a look around and im thinking mg def? Any help would be.......... well yea, helpful!
