Judging by the symptoms and the timing of symptom onset, I would suggest that this is a symptom of transplant shock.  How large were the plants at planting?  Potted plants?  What is the irrigation timing and amount?  What has the weather been since you planted them?  Different types of plants have different ability to withstand stress such as planting, so this may explain why one type is not showing the same symptoms as the others.  Or it may have been smaller, or had a better root system, etc.
