I think i read somewhere that falling ph can often be a sign of root damage/rot.
Something to do with over bacterial activity ???

yeh ya right mate.it sounds like pithium,that makes ph fall.Starts with a black tip on the end of the roots and then they die.u should be able to smell the roots rottin so av a good sniff.
