Plants Turning Grey

I've had my 2.5 minI bow running with my betta fish for a little over a year now, and my plants have begun to decay.
They were healthy and beginning to bud, but the leaves starting at the tips have turned brown. The new growth seems to have decayed and now i'm left with bare stalks. I trimmed off all of the dying leaves and new sprouts are starting to emerge.. but they may also be infected.
I'm not quite sure if this is actually an infection, but its what I've concluded so far. Introducing new plants to the tank only makes them turn grey and die off. I moved one small Anubis from my betta tank into my 10 gallon with my batik loach, and some of the plants have begun to get mushy and grey at the base..
I really have no idea what is happening to my live plants, has anyone experienced this decay before in healthy plants?

[EDIT]
The problem started in my 2.5 MiniBow kit. The broad leaves plant here started to decay after about 6 months of its addition. It was thriving prior.
(also note, the batik loach was only temporarily in this tank, currently resides in my 10 gallon)

The plant cropped on the left was some kind of lily that had very thin leaves and "contracted" the same problem within one day of being near the decaying plant.
I moved one of the plants into my 10 gallon. The ten gallon has these plants currently

The one directly behind the left log has already had its lower parts of the stalks turned to mush, plant was removed.
The small Anubis in the front of the right log had begun to decay in the 2.5 minI bow, but as advised by a LFS, I had dipped it in hydrogen peroxide
before planting it into the 10 gallon, which seemed to halt its decay.

I don't know what constitutes ferts but I use, API Leaf zone in my 10 gallon (containing inverts), and Seachem Flourish in my 2.5 (no inverts). They are in a 10 gallon (bought as a kit) with standard Aqueon LEDs and the substrate is a fine gravel from petco.

[EDIT] The plants most noticeably affected are the ones with smaller, more fragile leaves.
My Marrimos were turning white in my 2.5 Gallon tank as well. I rinsed and rolled them, and they seem to be healthy now. One of them was decaying from the inside out and had to be tossed.

 

Can you take a pic of the plants?

What kind of lighting and ferts do you have? What kinds of plants are having this issue?

I do not use ferts, They are in a 10 gallon (bought as a kit) with standard Aqueon LEDs

Please list the names of the plants that are having problems, and tell us what substrate and lighting you're using.

Rub the leaves of the plants and see if any residue comes off. It could be a form of algae

 

Are you using regular plain gravel? If so you may not have enough nutrients in the tank, if you're not dosing ferts that provide the necessary nutrients. (Calcium, magnesium, potassium, phosphates, nitrogen, iron, manganese, and carbon just to name a few)

Are you using the stock LED that came with the tank? You may not have enough lighting.

I'm using flourish and apI leaf zone to give them those nutrients. It is the same light they came with it, but it was doing fine for 6 months and now its dying

 

Plants are generally slow, and tough to die. They're pretty slow to show symptoms. Therefore it may have just barely got by for six months and now finally showing the signs of their stress.

API products won't be enough to provide everything.

I don't know of any stock lighting that's enough for most of the plants you're keeping.

 

Is there a way to replace the leds on my hood? If so, what's the recommended lighting for my plants?

 

Ditch the hood, get a versatop lid, and buy a planted tank appropriate LED fixture.

I'm not sure what an appropriate light fixture would be

 

Aquarium plants need daylight, the same as other plants. So, since we can't leave our aquariums in the sun, we use substitute bulbs.

The generally accepted LED for a planted tank is a full spectrum, 6500 kelvin tank light that is specifically designed for growing plants.

Alternatively, you can get an indoor gro-light and hang it on a stand above your tank.

Thanks so much!

 

No problem Planted tanks are a lot of fun once you get them right. Enjoy!

 

Just get Finnex Stingray. That'll be plenty if you have a better substrate.

 

Root tabs will help too... just place at the base of your plants (buried in the gravel). I also agree that the Finnex stingray clip on light (Amazon has it) would work very nicely for you!

Also, your ferts don't have macro nutrients.. NPK (Nitrogen, Phosphorus, & Potassium) which is necessary, seachem sells them separately, or you can ditch your flourish & API, & get an all-in-one like Thrive (I purchased Thrive on Amazon... they make "Thrive S" that's shrimp safe as well)

What are your nitrate readings? With your stock you may or may not need to add Nitrogen (Nitrate) for the plants

 

Are the fern and anubias planted? The rhizome (long twig like thing that the leaves and roots grow from) needs to be fully exposed or it will rot...

The anubias is fully exposed on its rhizome
