I think it is my bulb. I keep it on almost all day, but some of the plants are still turning a bit brown at the tips of their leaves and arent rooting :(
I got the biggest bulb at the store that covers the length of the tank, but it just ins't doing the trick. Its a uv light too so hmm.
But I put some plant food in the tank and got plants that live better in less light so I hope that will help.
I also should probably get co2.. but I actually don't understand what that does because I have enough fish in my tank to produce a good amount of c02
