i have some ambulia in my tank, that was for a few weeks vibrant and green. now the lower leaves are turning brown despite it still growing like wild, new growth coming off the stalks, and bright vibrant bushy tops. i have API root tabs in the gravel, and the bunch has been separated so it gets plenty of light. how do ambulia take up nutrients? should i add a liquid fert or stick with the root tabs?
they were transplanted about 4 or 5 days ago, within the same tank, but they were starting to turn brown prior. lighting is 72 watts in a 20L, substrate is regular old gravel... i didnt feel like dealing with the mess of the plant substrate i had in there before :)
