Go ahead and use it up. I use all kinds of fertilizers on my potted brugs. They are greedy feeders and dont much care how they get fed as long as they do lol..kinda like the chickens haha. Lots of people have different opinions on how to fertilze, what, when, how etc. I just use the same thing for all my plants, potted or not -and just kinda rotate what I use. I do alfalfa and compost teas, composted manures, vermicompost, sometimes I just use Miracle Grow fertilizer. I have too many plants to be picky about what I use for each. The one cardinal rule is make sure your plants are well watered before you fertilize. I also wait a few weeks before fertilizing new transplants and only give them a small amt the first few times until the roots are established.
