I found a 5-1-5 herb food fertilizer. Would this be good for a close substitute for the 5-1-3? It is a slow release.

Also, found a micronutrient citrus fertilizer as more of a supplement. Would you recommend this use? Thanks

I take it that the 5-1-5 is the ratio, and not the precentages. 5-1-5 ratio works for me. Is the micronutrient fertilizer a fertilizer with micronutrients or is it just a micronutrient package? - Millet

The micronutrient fertilizer is a supplement I believe. Not a full fertilizer. It is inorganic, and it had 2% iron and 1% magnesium, which may help the problem with my leaves, correct?

I have a question. What is the best way to fix these leaves if the above is not the best way. Will I lose all leaves that are yellowing? I have a couple that have already dropped.
