2 Questions: Is this a Magnesium Deficiency and what is this sack?

Hello Everyone,

This morning I noticed this sack at the base of my bonsai tree, is this just some kind of mold/algae or something else? I can't get a great picture, but it's milky white translucent, and the size of a quarter.

Also, I don't think my Rosette Sword isn't looking so great. It's about 2 weeks old, and I've started noticing yellowing on the edges, and now there's a little brown. Is this Magnesium Deficiency?

Thanks for any help!

The sack is probably some sort of fungus which is common on wood within 6 months after flooding. It will go away on its own, or many fish & shrimp will happily munch on it.

The leaves on the sword are the emersed growth dying off as the plant transitions to the submersed form. Most people will tell you to go ahead and trim them off. I usually suggest leaving them until the majority of the green is gone from the leaf to allow the plant time to transport most of the mobile nutrients out of the leaves. Either way you want to cut the leaf off before it starts to rot. This should be done by cutting the stem as close to the base as possible, taking care not to nick the new growth or the main portion of the rosette base.
