Anyone else see their dwarf sag start crowning under the substrate? They're in sunset gold caribsea sand with seachem tabs. Some of the leaves are starting to grow almost an inch below the substrate surface with some of the older leaves poking thru the sand. Could the light be reaching that far down? It's a 10 watt, 16" finnex stingray on a 5.5 gallon tank. It gives the appearance of regular growing dwarf sags but with sand thrown on top of them. Also when they do bust out the leaves stay really low to the ground.
