Leaf Margin Water Droplets…
Look carefully at this image as there is something important to notice. Looking at the leaf margins water droplets can be seen fairly consistently around the entire perimeter. This is an example of guttation which is basically the result from water being pumped up through the plant so forcefully that it comes out of the leaves. Overnight the humidity is high (in part due to the simple decrease in temperature) so it can not simply evaporate and it remains on the perimeter of the leaf surface.
However, this “water” is more than just plain water, it contains nutrients (salts) that when it evaporates from the leaf surface will burn the margins of the leaf.
The damage could be mitigated by washing the leaves in the early morning with water to flush the concentrated water off the leaves but this would add unwanted moisture to the environment so the resulting burn is just taken as a sign of riding the edge.
