I have a great big sword in my 54g. I'm not sure what kind; it has a little red tint but it isn't a red melon. If anything it just looks like an Amazon with some red if that matters. In any case, the old growth leaves are all wasting away. It started slowlyas some pinholes here and there, and I have been trying to stop it since it started but I can't seem to get it right. I've done two rounds of root tabs a few weeks apart, as well as regularly dosing Easy Green and supplemental potassium (which I read can cause the pinholes). I also have some pinholes on my red crypts and my lily, so I think it has to be some nutrient deficiency, but I have added a bunch of root tabs over time, plus the tank itself has an organic soil base under the substrate which i had hoped would last.
If you look at the second image you can see there is healthy new growth. I'm wondering if the damage to the old growth is done and I should just prune heavily or what. Thanks for your help 🙂
