Id check your PH level to start. Maybe nutrient lockout by looks of it, and or Magnesium Deficiency. Hope this helps.

What is this leaf showing?Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

Yellow leaves - new growth dark green. As health improves, can I expect yellow leaves to turn green?Once a leaf starts showing signs of ill health (yellowing, etc), what is the point of no return? I have been working with this plant for a couple weeks and can't seem to get the yellow leaves to "heal" - new growth seems healthy to me however. Any thoughts?
