possible iron deficiency across the yard (bay area)
I have been living in my current house for ~7 years now and for the first time I'm noticing symptoms in my soil that suggest leaf chlorosis.
I found that iron deficiency is the main possible cause (in my case I'm noticing chlorosis on the top new leaves primarily).
I'm not sure how the previous family who lived here took care of the yard, but I am trying to keep things organic and non-chemical as much as possible. With that said, I am wondering if this is a common symptom. What could be possible causes (e.g. topsoil erosion over period of time or lack of a specific nutrient in the fertilizers etc.)
Also, to cure this, is adding iron a sufficient remedy or is this due to another bigger issue at play?
I'd appreciate pointers! Thanks in advance.
