did u rinse your hydroton well? where you live do you have hard water?
Im using canna aque also.this same thing happen to me.i found out that it was my hard water I'm using.so i hard to get a ph down that has a buffer in it.
acid buffer if u have low pH to start with or and alkaline buffer. check your profile page i posted something on there.
