I have a planted aquarium that i set up 3 weeks ago, its low tech. On a 6 hour light cycle, using all the products md fish tanks from youtube is using... ive pretty much copied him. But some of my plants seem to turning brown. I do remember him saying in some of his videos the plants melt back? And grow new shoots is this true? Is this whats happening to mine maybe! Ive put up some pictures up.
