Have you tried adding calmag?

Just can't help but notice that like 60-70% of plant problems on this forum... are generally calmag, or Ph issues.... Re-watched an episode of the IT crowd today, n they got the answering machine running the help desk "IT.... Have you tried turning it off and on again? .....Your welcome." Made me think of the plant problems forums... "Have you tried adding calmag?"

Useless rant over...
