I haven’t fed it anything other then the grounds. If you have any good and easy idea for me to add I would be seriously thankful. It is in a lowes 5 gallon bucket
I know coffee grounds are supposed to be a good source of nitrogen, which is what that plant seems to be low on, but if you're just putting the grounds straight on the soil they're probably gonna take a while to break down. I'd go with something a little faster-acting like the Alaska 5-1-1 liquid fish fertilizer, which is available at most hardware stores (in the US at least). It's strong stuff so don't give more than recommended on the label.
For longer-term, like to get it through flowering in that pot, I'd follow up with a few cups of compost or worm castings (store-bought is not ideal but is okay) and a top dressing of dry fertilizer. Personally I use Espoma Tomato-Tone in flower, but just about any all-purpose dry fertilizer blend should be fine, just go by the top-dressing recommendations on the label.
Edit: for that size plant in that size pot you're probably gonna have to top-dress every couple weeks in flower. Or if you're feeling ambitious then transplant it directly into the ground, with some compost and fertilizer in the hole.
