I'm not sure what you've got going on. If it's the older leave turning yellow, I'd try spraying with seaweed extract like Maxicrop or Seasol mostly for the potassium. If it's the younger leaves then spray with an iron supplement. |

This is a very nice flowchart for identifying nutrient deficiencies: http://landresources.montana.edu/nm/documents/NM9.pdf Scroll to the 6th page and just follow the questions. I would also say this is a iron deficiency. |
