I will have to check the leaves I guess, next PWC. The light has been on the java fern for about a month or so now.
When I first got my new light I moved it from my low light 50 to my 20. It was in bad shape. I have gold barbs that have been munching on it. But after about 3 weeks in the 20 with more light and no grazing fish, it started showing a lot of new growth. But now some discoloration is happening and I was concerned about a nutrient deficiency since I have more plants now that I'm feeding.
