I have so many pertinent questions: what is the plant; is it a houseplant; what does "young" mean; is it in the ground or a pot and where do you live. For most plants, the need for fertilizer is slowing down as plants prepare themselves for winter. Using a balanced fertilizer at half the recommended rate is all I can suggest with the info provided. Another option is a layer of compost worked into the top 1" of soil. If your plant was recently obtained, I wouldn't fertilize this year: let it work on establishing roots, not top growth.

Though most vegetables are heavy feeders you do need to make sure you do not feed too much nitrogen; as this will inhibit fruits and vegetables.
Manure must be properly composted and is high in nitrogen.

When it comes to fertilizing, more does not mean better. It is possible to overfeed your plants. Too much fertilizer can damage and maybe even kill your plants. Before applying any fertilizer, it’s a good idea to have your soil tested so you can select the type and formula that suits your plants’ needs. In return, our plants will reward us with bigger flowers, bigger leaves, and bigger fruits and vegetables.

Lime is mostly calcium and is used to raise pH. It would take hundreds of pounds to make grass do poorly depending on what your soil pH is now. I'm not sure it would kill it. It takes 5-8 pounds per 100 square feet to raise the pH by just 1 point. Since you will ruin the soil, why not go with solarization to kill grass and weeds?
