Transparent dying plants? Nitrogen?

So I've had my 29 gal set up for a 6 months now. Community tank with about 15 community fish. Here's the tanks specs

Tank: 29 Gallon
Filter: Stock HOB
Light: 30" T8 Fixture
-Full Spectrum Bulb
30" Deep Blue HO Dual T5
-1 10k Bulb
-1 6,7k Bulb
Substrate: Eco-Complete
Ferts: Iron, Potassium, Seachem Envy, and Phosphorous (weekly)
Co2: Fluval 88g (just added 3 days days ago, previously used Excel)

Here's a pic of what the tank looks like:


I recent acquired a few plants from a fellow PTF member a week or so ago. All of them are doing great, some I've already had to trim. Two plants in particular are not doing as well in the tank. The red lily (Nymphaea Stellata I believe) and the Dwarf Sagittaria are both turning transparent and dying off. I've had the lily for months and started it from a bulb pack and has always done great until a week or two ago. The dwarf sag was one of the newly acquired plants and has been on the decline. Here's a pic:



I've been doing some research and think it might be a nitrogen deficiency? I don't add nitrogen currently so leads me to think it might be that. Whats really weird is both those plants are fairly low-moderate light plants where as my medium-higher light plants seem to be doing better but are showing minuet signs of the same deficiency. I haven't done root tabs in this tank in a few months, might that be the usue and or would it help?

Here's a pic from another member on nutrient deficiencies and what they normally look like:

It sounds like the dwarf sag is melting away. I had this happen with some of my dwarf sag I got on TPT, but it ended up sprouting some new leaves after most of the originals melted off.

Thanks for the response ngrubich. I've seen that diagram in the past and use it as a reference from time to time. Good to know that yours melted and came back. Guess that explains that but still unsure on the lotus. It's still creating new pads every week and I constantly have to cut them back as they already take up a quarter of the surface. The bottom big leaves just seam to be dying off though. They are very large (size of my hand) so wonder if I should just cut it back more to promote new ones or simply need to add a deficiency I'm missing. I did add a dozen or so root tabs broken into halves and spaced around the tank so hopefully that helps.

It sounds like the old leaves are showing signs of deterioration. Is that the case? Or is are the new leaves deteriorating?

If it is the old leaves, it is likely nitrogen.

If you can post a few more (close up, high detail) pictures of the deteriorating leaves, particularly pictures of broad leafed plants or stem plants with larger leaves it would be helpful.

This will melt away and new growth will come. What is the tank temp? This dwarf sag came out of an unheated tank so maybe the temp difference is the cause? Ive seen it happen before where the old growth goes transparent then deteriorates and then the new growth appears and then this stuff just takes over.

With lighting mentioned and recent addition of CO2,,plant's may require more than once a week fertz.

This.

And both those plants would benefit from a root tab or two.

Good to know, thanks all. I put in root tabs so I'll give it a few days.
