Perhaps were you to fill out the troubleshooting form, (copy-n-paste it here, answer the questions as completely as possible) you'd get a couple responses. Answering the questions below would help also...

How large of chunks of lime? (chunky or powder) How much per gallon of soil? What kind of soil mix, and are you sure it wasn't pre-buffered? What was your runoff ph before buffering the soil?
How old are the plants? Growth or flowering stage? Have you looked at the sticky about epsom salt not being the miracle cure? Or seen one of the mollasses threads...? (I've personally used mollasses in place of CalMag Plus for years)
