Anyone using Earthbox or something similar?

I am using 4 earthbox systems and I need to replant but don't want to buy the replant kits. I was wondering what I can use for the fertilizer and dolamite I need and how much.

From the EarthBox web site , the kits include:
  • 16 ounces of 7-7-7 (N-P-K) fertilizer
  • 16 ounces of dolomite
  • 2 cubic feet of potting mix
The fertilizer breaks down to 1.12 ounces of available Nitrogen, Phosphorous, and Potassium (N-P-K), in other words, a "balanced" mix of macro-nutrients. For 4 boxes, the total quantities are 4.5 ounces of each nutrient.

Dolomite is available, I think, at pool supply stores.

Potting soil is widely available.
