All my plants are putting out new leaves except a couple of Echinodorus parviflorus. I have planted them ~month ago with fluorish root tabs next to each. Each of them have a few leaves of different sizes from old to new. All leaves look fine, no yellowing, wholes, etc. They just not growing. I doze fluorish and potassium on weekly basis. All other plants grow new leaves, even Java ferns manage to get a few new leaves out. But Echinodorus parviflorus just sitting there.
