For some reason, my hornwort is yellowing a bit. I heard that hornwort should be able to toleratre a bit of salt. Right now, I have a 20H and maybe about4 or 5 tablespoons of salt in there in a small cup. I have a 2.5wpg, a 50 watt light fixture I made. I put in about 1 tablespoon of the kent freshwater plant a week, well usually 2 tbs. I will start DIY co2 again. What could be the problem? Also, is it like a stem plant so that I can cut a tall one and just plant the half in?
thanks
