Please help - Brown on Leaves (pics)

Oxboy555(Las Vegas)September 20, 2013

What do you think?

As you see, I live in Vegas. This plant received about an hour of early morning sun and the rest off the day all shade.


Overfertilizing? I was giving it a monthly dash of diluted fish emulsion and seaweed extract in water over summer.

Something else? These brown blotches are not on all leaves. Random distribution it seems up and down.

Looks like it could be damage from fertilizers. Salt damage usually shows up on leaf tips and margins.

I agree that salt damage (in the form of applying too much fertilizers or planting near where the city sprays salt to roadways when freezing weather arrives) is possible but research also some fungi called brown blight and brown blight. I tend to see those more on tea camellia though.

Fish emulsion and seaweed extract are weak fertilizers that do not normally have mulch NPK, especially considering that you add them once a month.
