    3 weeks ago I noticed a few of my Glosso leaves starting turning red from the stem + the stem also started to get a red tan.
    Since then I've noticed 10+ leaves turning red and plenty more stems. The first red leaves are starting to die off and decompose.
    I'm struggling to understand what's happening.

    60L heavily planted
    Lighting is reasonably strong (not sure exactly what kind of set up I'm running for lighting)
    DIY co2, 3 bubbles p/s on average
    6.8 ph but did swing a little 6 weeks ago
    Seachem Flourite Black Sand
    dosing 1ml of seachem flourish trace every second day
    tiny bit of blue algae which i'm controlling with Hydrogen peroxide spray (tiny dosing, doesn't damage riccia or other mosses)
    external filter 600L h/r with strong flow

    Set up just under 3 months ago.

    Any help/tips is greatly appreciated.
    If photos make a difference, I will upload some tomorrow.
    Many thanks,
    Nikola the noobie (~:

    Hey Nikola,

    I'm no expert, but if i had to guess I'd say they need some feeding. You are dosing trace nutrients but no macro nutrients. Apart from carbon these (N,P,K) make up the bulk of the plant and are needed for most functions, so they need them to grow.

    Maybe try dosing some ferts.

    Try take a picture. Nitrogen deficiency do make plant red

    It's an N deficiency. But it looks pretty cool, doesn't it?
