What's killing my plants?

Plants were doing great a week or so ago. It was time to fertilize them, so I put a small amount of aquarium root fertilizer tabs under the sand in the tank, and now this has developed:

What is this that is growing on the leaves, and how do I get rid of it?


Thanks!

Someone else will probably chip in, but I think it like algae? Possibly, maybe?

It would help to know your setup, lighting, tank size, ferts, co2, etc.

That looks like hair algae maybe.

Looks like the beginning of black brush algae

Don't know it looks like BBA or not, but it's definitely some sort of hair algae. Probably caused by excess nutrients in the water.

You can try:
Dosing small amounts during the week rather than large amounts at WCs.
Dosing Excel.
