Plants get ferts from both roots and through the leaves. Obviously yours are rather hindered from getting them from the leaves right now from the algae.
When the plants can get ferts from both ways it's easier for them to get what they need.
So in your case they might appreciate it more than usual. Need, no, benefit, yes.
