A couple of months ago I had a similar problem with new leaves on
Echinodorus parviflorus coming out deformed and lacy. Due to the hard water
here,  I knew it was not a Ca deficiency, and I focused on boron. I treated
the tank with a high dose of the trace element mix that makes up the PMDDs,
and bingo, problem solved.
My previous fertilizer treatment was daily Dupla-24 drops, and occasional
nitrate and potassium additions. Now I add several ml of the trace element
solution daily and have not had any recurring problems with the
