I can't help much there. I tried growing a lace plant (maybe
Madagascariensis, maybe something similar) once and it didn't flourish.
The leaves never got very large, they were thick, fairly rigid and cupped
downward. I never thought about it before, but that growth pattern could
be consistent with calcium deficiency.
A. Mad. has a reputation for being difficult to grow. I imagine that my
problem could have been a lot of things besides calcium deficiency. Among
the other possible causes was the fact that I didn't really care that
much. I got a smoking deal on the plant, then realized after I got it
home that if I did get it growing well it would quickly outgrow every tank

I got mine at the neighborhood grocery store health supplements section.
Similar tablets would also be sold at pharmacies. I just looked for
tablets with calcium carbonate as the calcium source and the smallest
number of other ingredients.
