I installed my flooring last month and I just noticed a small crack in one of the planks. How would you recommend repairing it?

Hello Mike and thanks for your question. Not sure how big the crack in your floor is, or where it's located, but the easiest way to remedy this would be to take off the base board that is parallel to flooring nearest to the plank, and unhook the flooring plank from the wall back to the damaged plank. Remove the damaged board, and then replace it with a new (leftover) piece, and reattach all other plank, working your way back to the wall and then reattaching the base board. There are some good installation videos available on the product page of the Lowe's website, and also many others plank replacement videos can also be found online. Hope this helps. Thanks again for choosing Style Selections Luxury Vinyl Plank Flooring.
