The app is telling me to fertilize and I don't know how. ...

Gregs fertilizer feature needs a lot of tweaking I noticed. I agree with @SteffyHazPlants! I use a liquid fertilizer that I just follow the dilution instructions on the bottle. I fertilize with every watering, but depending on your environment starting with every other watering can be good to monitor fertilizer burn. 😊
@Kapuac it definitely does. I actually turned mine off and manage in my own now since I use the dilution watering method too.
