Most of the Acorus you buy from the stores are grown emersed, and are
very difficult to grow sumberged. I'm not surprised you are having

The driftwood could be the problem. Also, you could have soft water,
with very little buffering capacity. Ideally, the carbonate hardness
should be 4dKH or higher. Ordinary baking soda (not baking powder)
can be used to boost KH. For a 50 gallon tank, try adding 1/2 level
teaspoon at a time till you gradually get to the desired hardness.

The carbon could be removing nutrients that your plants could use.
