RE: Plant Nutrients

I did not read every portion but I have to assume you have not done a foliar analysis at a lab?  Without this, you really cannot determine what is going on.  Get that done and I think the light bulb will go off.  When I did my foliar, I came upon issues that nobody knew about and ever dealt with here in the desert of AZ.  It was truly enlightening.

Really, don't assume anything and get the test.

Good luck!!!!!!
