    Hi,

    Can someone give me advice why my limnophila sessiliflora, staurogyne repens and pogostemon helferi don't will to grow. Rest plants are ok I think.
    I run co2 and have 1 ph drop at lights on. Using EI method and run two fluval fresh and plant 2.0 46w, first on 100% second on 30% intensity for 7 hours.
    Tank is 108/42/45.
    Thanks

    Tank is restarted three months ago, all plants are from minimum a year. Limnofila grew good, but stopped, rest stay stunned all three months.

    Hi all,
    It depends, some USA based recipes leave it out, because their limestones have under-gone "dolomitization", in Europe it is more of a mix <"some areas have magnesium in their aquifers">, some don't.

    cheers Darrel

    Hi all,
    Plant health doesn't look too bad and not magnesium deficiency.

    It is difficult to tell from the photo, but are the growing tips of the stem plants paler green? (Like this <"Rotala rotundifolia").

    The look like they might be in the photo, but it may just be an artifact of the higher light intensity (nearer the light) causing flaring in the photo.

    cheers Darrel

    Hm I thought EI has enough Fe and my ph is never above 7.4, even at night, but will try to add different source of Fe to see what happens.
    Thanks

    Hi all,
    Plants don't need much iron (Fe). It is one of the easier deficiencies to diagnose, because iron isn't mobile in the plant, so deficiency effects new leaves. It is only really iron (& manganese (Mn)) deficiencies that cause chlorosis (the yellowing) in the new leaves. If the new leaves are pale? iron deficiency is likely.
    Have a look at <"Fe EDDHA"> and linked threads.

    cheers Darrel
