Default Re: Deficiency or excess

Hi tanksalot,

My first thought is an iron deficiency with the interveinal chlorosis (yellow areas between green leaf veins) however usually only the younger leaves are effect. The second possibility would be a potassium deficiency which usually exhibits chlorotic and then burn areas along the margins of older leaves.

What are you dosing for fertilizer?
