Hi everyone. Not sure if anybody can help me but my hornwart has started to turn brown and disintegrate along the bottom of the plants. I've tried to tack them down by tucking it into the substrate so maybe that's what does it? The tops are very green and only inches from a really really bright LED (finnex ray 20). I dose excel daily and give Seachem Flourish 2x/wk. Nitrates are always < 50.
