Nymphaea pubescens losing leaves

I have two lovely Nymphaea pubescens in my 8 gallon, low tech tank. The substrate is Eco-Complete. I have one lily that is losing its leaves. The stems seem to be disintegrating. Am I not adding enough Flourish Iron or Flourish, or do I need to use root tabs, or is this another deficiency?

Bump for help! The temperature of the tank is 78.6 F. Maybe it is a Potassium deficiency?

How about some photos of the problem?

Also, pictures of other plants in the tank would be helpful.

We need to be able to see new and old growth on the plant.

Also, do you know about the aquarium plant club in CT? CAPE usually meets monthly and is a pretty good place to meet other aquarium enthusiasts. Amanda is running the club now.

I don't have any experience with this plant, but some general web searching suggests most lillies, including Nymphaea pubescens are heavy root feeders, thus would benefit from root tabs.

Also, are you dosing anything other than Flourish comprehensive and Flourish Iron? NPK are all important, and very little of these nutrients is supplied by Flourish.

N and to a lesser extent P can be gotten from fish waste if your water changes are not overdone. However this has its own drawbacks, and may prefer doing large W/C's and adding nitrate/phosphate after the water change (it is also less stock-dependent this way).

I can take some current photos, but I do not have any good old photos. I never heard of CAPE and would be quite interested in joining.

I should pick up some root tabs for my two lilies and grab some fertilizer for the NPK nutrients. Thanks!

Here is a photo of the stem disintegrating. This stem was fine yesterday and now it looks like the strands of cellulose are no longer holding the stem together.

Can you post pictures of the other plants as well?

It is hard to tell from that one photo if there is an issue.

Is it just that one leaf going bad or are there others?

There is no problem with the plant...they do that some times to recover...give it a month or two and it will grow again
