Hello, my hornwort I bought about 1-2 weeks ago grows every day, but the leaves just turn yellow/brown. I’m not sure why. Also new leaves grow on my other plants, but usually they come shriveled, I’m not sure on why. Also my moneywort/creeping Jenny grows nicely but from the bottom where I have planted in the substrate starts to melt and turn yellow, causing them to float. I have sand mixed with eco plant substrate. I have 10 root tabs planted underneath the substrate near every plant. I dose flourish twice weekly. Btw it’s a 75 gallon tank. I have a 110W light and it seems to be doing fine. I also have 3 diy carbon systems with 2Liter bottles. That diffuse co2 nicely during the day time, where I turn them off at night. I give them 12-15 hours of light a day. I don’t know why I can’t get this right. I’m struggling to keep my plants alive and I don’t like to see dying or decaying plants in the tank, it just doesn’t look nice. All of the plants are fairly new and I am hoping to find out what I’m doing wrong so I can fix it and have a healthy planted aquarium. Thanks I hope someone can help me.
