why are my vallisneria leaves browning?

Yeah, patience is key. Mine took a few weeks to show improvement after I made changes. Also, if you're using liquid ferts, make sure they're balanced. Too much of one thing can throw things off.

For sure. I've found that Vallisneria does best with a steady routine. Once you dial in the right balance, it'll take off.

One last thought: check for algae on the leaves. Sometimes browning can be algae blocking light. A gentle wipe with your fingers can help if that's the case.

Good point about algae. Also, make sure your tank's not too warm. Vallisneria prefers cooler temps, around 72–78°F. If it's higher, that could contribute to the issue.

Yeah, temp's another thing to watch. My tank runs at 75°F, and the Vallisneria's happy as can be. Also, avoid sudden temp swings, they hate that.

Lots of great advice here. OP, let us know how it goes after you try some of these fixes. Vallisneria's a tough plant, so with a little tweaking, it should recover.
