    I'm not sure about the color balance of these images but if they are slime-like dark blue-green, they are very likely cyanobacteria. BTW yellow leaves are caused by lack of quite lot of nutrients: Fe (if leaves are young), N, P, Mg (and lack of Fe at young leaves growth stage) if leaves are older. But mixture of algae/yellow old leaves usually occurs in my tank at low levels of P.
