@BobbyLane I been thinking of how to explain this thing in regards to those beech leaves.....
This here pic is a good illustration....ish....
I got this theory which may well be summed up by....
Leaves wearing out due to CONSTANT transpiration in the leaves.
Don't know if it's scientifically a thing.
But there is a constant here in these trees, be it beech, elm, maple, even pines.
Seems to show its ugly face when folks feel the need to keep substrates wetter, or more organic, because they fear things will dry out.
That is not the cure of course.
Loose soil across the world, with appropriate watering frequency....that's the cure.
Something about
@milehigh_7 teaching of soils in the desert, he can't use organic or stuff boils.
We know nursery soil works in some instances.
I believe those instances are successful because of the position of the pot and/or its temperatures.
Point is....it's kind of like everything else.....
Where folks use a backwards cure, which doesn't really help so they change one more thing, and they end up at 75% well.....
When they could have just done the exact opposite of what they thought was the cure....
Skipped a step, and been at 100% well.
Basically....
Think More...
React less...
Simple simple simple simple simple!
