Interesting article. And in most cases, their recommendation to limit phosphate works since most community tanks are full of organic phosphate that is not testable by conventional PO4 test kits. But in an established planted tank, all that matters is proportion. 10-1-20 for N-P-K.
I've actually added orthophosphate to reduce algae. The reason being, as I understand it, is that algae is opportunistic and can take advantage of any one nutrient excess, while plants need all in proper proportion.
