Continuing along the lines of my post about the leaves on my blueberry plant, I thought I would post about this one. Right now about 20% of the leaves are turning yellow. A few of them (see the second photo) have tiny red dots on them.
I suspect that, like the blueberry plant, this one is also just following it’s natural progression late in flower. But, I want to be certain and I also want to get better at identifying deficiencies.
So - I believe the yellow is just indicative of a nitrogen deficiency. The red dots however… the closest I could find in my photos of deficiencies I’ve collected is a manganese deficiency. But it doesn’t look exactly the same, so I’m not sure.
