Thats just a lil bit of rust rust-colored spots on marijuana leaves indicate a fungal infection or a deficiency in magnesium or calcium. Nutrient burn is also a possible culprit. i dont think its a fungus, those you can rub off.. mayb its a lock out, she had enough for now i think. flush her with just water so it wont get worse good luck

Calcium deficiency. Definitely not "rust" or due to cool night temps. Absolutely no need to "flush".........add a cal/mag supplement to your line up, or increase the dosage if already using a cal/mag supplement.

Could be phosphorus deficient, or could just be from cooler night time temps. I've found below 70F that purple leaves can occur and it's ok/normal. Mine do this when the temp drops below 68F at night. Hasn't effected my outcome to this point on my grows and looks cool to me, so I don't worry about it. Just my thoughts. Best of Luck! Happy Growing!
