Okay, that sounds like too much lime. Problems with soil pH going HIGH aren't all that common in soil.
Just out of curiosity what are you using to check pH, and if it's a meter, have you calibrated it recently?
High pH often has its own 'look' to it, which is why I guessed at low.
Lime gets used up over time... this is why I tell new growers to go with a humus based medium rather than peat. It has its own internal pH buffers that don't depend on an outside substance [lime] to correct for the inherently low pH of the substrate [peat].
