 is to look at the numbers. There's usually the NPK, the nitrogen, phosphor, and potassium, and it's three numbers on the bag. And if the first number is extremely high, like let's say it's 30, that's the nitrogen, you can tell that that's too much nitrogen. It's probably synthetic. But if it's like around 8, you know, if you have like an 8-5-8 mixture, let's just say, then you know that it's safer. It's much more naturally derived. Okay, so that's fertilizer. What about weed killers? What about things that kill things?
