Used 2% water brine, but did not take carrots into account. Will these still ferment safely?

New to fermenting veggies. I measured out the water and salt for a 2% brine but realized that I didn’t weigh the carrots to take them into account. So the brine is only based on water weight. Should I add a little more salt to the jar?? It’s only been a day so they are still in the early stages of fermentation.
