I'd watch the dish liquid. Some of them have chemicals in them like formaldehyde, and that can kill your plants and poison whatever fruit or vegetable your growing. Read what is in it and make sure there is nothing toxic in it, or you could end up either killing your plants or making yourself sick.
If you need something for stick, try something like vegetable oil, or something else you know you can already eat.
Don't use something like dish liquid. You don't know what you might be doing to your plants and yourself.
