From: Rebecca Allbritton <rda at tamu_edu> : I have misshapen new growth on a lily plant. What nutrient is the tank water missing? Rebecca, without knowing anything at all about your aquarium (substrate, fertilization, etc.), I can only take a guess. I have seen hygro leaves crinkle when calcium is in short supply. If your water is very soft this may be the culprit. Cathy Hartland Middletown, MD
