Why are my floating aquarium plants deteriorating?

[Clack]

I've got frogbit and another plant, not sure what it is, both are dying off pretty fast, is it fluxx?

If you're not fertilizing, that's probably the issue

Lack of light's a big one.
Too humid's another.
Disease is a possibility too.

Even with low lighting, does that still cause issues. How many hours does @Panadalover93 light the tank for.

@coltin said: too humid.
I've heard aquatic plants can struggle with high humidity. @Panadalover93, what's the temperature in your tank.

tank room's at 80, AC keeps it at 72

I don't fert, that's the issue.

My setup's working, 1ml of Flourish for 5 gallons, 1-2 times a week. I've got a small school, 4 guppies and 4 endlers. Lighting's on for 12 hours.

Temperature seems fine, 80 in the tank room with 72 with AC is within a good range.

Frogbit's also losing its roots, no idea why, and the tips are dark, almost black - fluxx, anyone?

This one, roots falling off, dark tips, got me stumped

That's enough.
