This has been a well known issue. If you're persistent, you may choose to grab a spade (not a rake) and remove what you've planted. It will still show the weeds right after doing so, but by removing your crops, everything will go back to normal... eventually. The "weed effect" should disappear after re-planting your crops and they begin to grow, but if it doesn't, just re-plant because it will eventually work.

I know this from experience.
