Non substrate feeding plants would have a hard time if all the nutrients are in the substrate. So you limit your plant selection which is fine but some people prefer others.
Also if your water's pH is 7+pH, the chelated micro/iron only lasts a few hours before they become unavailable to plants & algae.
I've found a jungle tank packed with plants always control algae.
