    I think my Hygrophila Corymbosa and Rotala Macrandra 'Narrow Leaf' are suffering from some sort of deficiency..!
    I just cant figure out what exactly it is ...!
    All other plants are doing well except these two..!
    HC leaves are curling at the edges & RM isnt turning red and bottom leaves are disintegrating... Though Macrandra is new plant in the tank just transitioned from the emersed growth.

    The water i use is groundwater which is substantially harder than average hard water..! But no Chloride/Fluoride issue though..!
    Fertz: Seachem daily lean dosing.
    Substrate: Amazonia Light Normal type (2 Inch depth)
    Tank Dimension: 48Lx18Dx30H (Inches) Fixture stands 4 Inches higher than the tank
    Light: 6x22W + 100W Flood light 6500K (8 hrs Photo-period)
    Using pressurized CO2

    My guess would be lack of light from shading, or lack of flow to supply nutrients/co2 in that area. It would be nice for one of the gurus to chime in with some more advice.

    Are we sure that macrandra narrow.
    Kinda looks like rotala rotundifolia.

    Off to the right, in the second picture, there is some, what looks to be, stunted ludwigia ovails. It has some green hairy algae and has lost most of its lower leaves. I'll let you give the diagnosis phishless. Thanks for coming to the rescue one again lol

    I'll go with ludwigia species and most ludwigia I've had will drop lower leaves if shaded.

    Not so sure about coming to the rescue part. o_O

    At first glance I'd say a macro deficiency.
    Seachem daily lean dosing is very weak IMHO.

    I've also never grown Hygrophila Corymbosa.

    @Neil what are you dosing and do you have any water parameters?
    Lots of light with CO2 and lean dosing is suspect.
