2 weeks is a blink of an eye in the scope of things. It's also not a good idea to start a tank with only slow growing foreground plants. IMO foreground plants need a support system of other fast growing plants to thrive, they should be planted last after the tank is established. If it were me Id remove large pieces of dead organics by hand and lightly gravel vac the rest. Clean filters and add a good layer of pollyfill (filter floss) as a final stage if possible. This will polish your water & trap incredibly small particules. Dont forget to change this out often, pollyfill is cheap! Get some hornwort in your tank, don't forget to fertilize on a regular basis along with maybe a few fish with a small bio load. I like guppies who seem to pick on anything they see! Don't over feed, they will clean more if you keep them hungry! Adopt a regular maintenance schedule as well, water change, filter cleaning, trimming, ect. Successful planted tanks are grown, this take time, work and patience. They aren't a plug n play hobby like many videos on the youtubes lead you to believe.
Also if you populate with guppies watch adding ANY females or you WILL get babies
