    Reduce your parameters to N<5 or N=5 K=N P=N\10
    Now you have overdosing NPK. I think your aquarium is very young and you began to dosing npk very early, now plants have a period of adaptation (if your aquarium is young really)
    And what do have kH and gH? Maybe your water is very hard..
    How old is your aquarium?
