    IMG_2173.JPG IMG_2172.JPG Based on these images is my hygro suffering from low potassium? I've done a little searching but I just wanted to make sure. My other plants are not showing the same symptoms so I'm just curious, I read somewhere that potassium is the first to be depleted in a soil based substrate however I think it's bit a early for that to have happened? This tank has only been up since the last week of July. These are mostly older leaves however some new leaves here and there are showing the same thing.

    May or may not be relevant, but if they were trimmed and replanted recently and haven't yet rooted well then they will be using water column only, not the soil.

    If it was any other plant then it's almost certainly low K.

    But Hygros do this same thing when micros or Fe is too high. So depending on what you're dosing, could be that too.

    Hmm really. I dose flourish and I was pretty heavy with it but I recently did a big waterchange to remove some dirt that surfaced and now I'm just dosing flourish once a week. I guess I'll keep an eye on my micros and see if that makes a difference

    The yellowing along the tips and borders and nutrient deficiency
    the other with pin holes and no yellow borders to it, is the general Hygro issue which may or may not be related to Micros (still being debated)

    That's what I figured with the yellowing, so I'll pay more attention to the micros and up my potassium when I get some.
