Fertilizer can be purchased online from either Amazon, eBay, or Drs. Foster & Smith (plus I'm sure many more other sites). Seachem Flourish Comprehensive Plant Supplement is one of the best, as it includes all of the nutrients needed for plants to grow well, unlike many other fertilizers which only have 3 or 4 of the nutrients. To get optimal plant growth you'll probably want to invest in a bottle, which will last for months.
