Leaves curl, become crispy and have weird colors I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Brown rust spots on oldest leaves Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Do I have to worry?Only on one leaf of one plant. Is this some fungus or virus? It looks a bit like coffee rust, but I couldn't find anything else like it. How should I proceed? Thanks in advance!

leaves dry and curling up Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Spots on leaves Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?
