Just wondering if anyone has seen this before. One of my plants (blueberry muffin clone) has spots on most of the upper leaves. The plant as a whole seems fine, and the buds look normal, I’m just wondering if this is something to be concerned about. I’m growing outside, no sprays or fertilizers. This plant is about 6 or 7 feet tall and is surrounded by other plants with no spots on their leaves. I would not say it’s a nutrient deficiency since all the other plants are doing fine in the exact same soil/location. I’m not particularly worried about it, just curious really.
Looks like possibly a calcium or magnesium deficiency. @Covertgrower any thoughts?
Difficult to say for outside grows with pests as a possibility. The brown spots pictured in the Hand look possibly potassium. The other spots look differently than the one in the hand.
With out a clearer picture the white spots could be a fungus of sorts.
