ph should be 6.0-7.0 did you amend you soil with leaves, mulch, old horsemanure and some lime............if not you can still ring around it with a litttle lime & old horsemanure............cut off the head on a slant right under the floret...........you can still eat it..........you have to check them every day as they will grow & ripen fast. be sure to soak that in ice cold water with salt to get out any hidden bugs..........more florets will come on your plant.
