How old is your substrate? Judging on your joined date, if you revamp your planting without restarting the tank itself probably defeats the purpose of replanting in the first place. If you restarted, maybe the plants you got are not conditioned to your tank's parameters, or just non-hardy plants that need an experienced hand to grow. I suggest you take a picture of the plants for the experienced peeps to diagnose for you.
