Having some discoloration on the fan leafs. From a quick Google it seems to be related to nitrogen deficiency. Would adding some coffee grounds or other organic matter quickly reverse this?

Leaf Yellowing?What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?
