I have 2 outdoor plants and the leaves in the middle section of the plant are turning pale yellow and dying. The yellowing starts on the ends of the leaves and slowly works its way in. I have Fed them some flower nutes that contains nitrogen,potassium,phosphorous,calcium and zinc also with blood and bone aswell as some sulphur nitrogen type of fertilisser but none of them have worked and the leaves keep dying working its way up. could this be a magnesium def, potassium def, nitrogen def, zinc toxicity or nute lockout? pls help
