You can add all the calcium in the world to your soil, but if you don't consistent or regularly water and keep that soil damp to allow the calcium that you have already in your soil to be transferred from the soil into the plant due to that moisture being in the soil, allowing that transfer to take place, you're going to have the problem over and over and over again.
