Yeah I think part of the problem was a magnesium deficiency. I bought some MgS04 seems to be helping a bit. However, I believe there maybe more deficiency now. Some of my fan leaves are brown in colour near the top of the plant. Also a couple of my plants are showing lesions/spots. In detail, the leave is either lime-green with splash of yellow and a small lesion where the yellow mark is or brown with splash of yellow and small lesion. Also new growth a looking like a severe mag def (yellowish or green veins with yellow intervenials) Now from looking at "plant soultion and problems" (genius post) I want to say this is a boron deficincy, zinc or maybe a calcium which cause the mg deficiency to begin with? Thoughts?
