Could this be from a lack of CO2? OR...a little back story first. I was suffering from a severe case of brown algae, so i removed everything from the filter to the plants, to bleach, not the tank or the gravel. So here i have arrived with some of my plants lookin really bad. My rotalas' leaves are becoming transpaarnet also. But the picture I've posted looks more severe the the rest of the tank. ANy suggestions?
