There can be a few causes to this. Cool temperatures, along with a lack of humidity can cause this. So can underfertilization, and pH imbalances.
I recommend keeping dolomitic lime and iron sulfate handy, and applying this every few months. This will keep the soil healthy, and replenish the most commonly lost minerals to the soil, as well as keep the pH from swinging too rapidly too often.
