Cauliflower heads not forming
The plants look great, but as of yet don't have even a beginning of a cauliflower head on any of the 4 plants I planted. Any ideas?

There are several reasons your cauliflower may not be heading. Too much nitrogen can give you more foliage growth and little to no head formation. Adding more phosphorus can help with this. Your pH might be off--cauliflower likes a pH around 6.5. More imprtantly, they need cool weather in order to form heads. You can help keep them "cool" by placing mulch around the base of the plants.
