Re: distorted shoots

My first guess, here at work without references, is Magnesium. I found that
the java ferns and the swords are heavy Mg feeders. I believe you use
Milton tap water, right? Check with your water authorities for the Mg
content. Calcium is similar.
Good luck and let us know what was the cause.
