What are the main contributing factors in a Cyno outbreak? Fix?

I've been experiencing the same thing and the only idea I have as to what caused it was changing my lights. I recently modded an Aqualight pro to have the MH plus 4 T5HO's rather than the PC suppliments. When I went to get the T5HO bulbs, Mike at hidden reef convinced me to try some new ones he had (50K) and I'm suspicious that they are causing the problem.
