Help with nutes

They are pretty close to harvest and I would suggest not giving any more nitrogen/nutrients, they will finish just fine if you continue with what you are already doing. The leaves going yellow is normal and is due to your plant reabsorbing the nutrition in the leaves for use as an energy source to mature the flowers. It is more efficient for your plant to do this, rather than grow flowers AND make nutrition from new during this stage of flowering, and is one thing defoliation advocates fail to understand. Cannabis needs the old leaves as a fuel/nutrition source for when she is flowering. Removing the leaves while they are green means the plant must divide her energy between growing flowers and making nutrition (carbs, sugars, amino acids etc) from new, whereas had the leaves been left on, the plant can use nearly all the energy for flower growth and obtain her nutrition (carbs, sugars, amino acids etc) that she has already manufactured and "stored" in her older leaves and waiting for use during flowering, and this is why the so called "fade" happens and why the older leaves will go yellow on otherwise healthy and well fed plants during flowering.
