cmasfca, I have some unsolicited advice that will help if you are not doing it already...

It took me a little while but I have this little friend call Mr. Clipboard that I recommend beginner and intermediate growers keep handy at all times. I was growing for some time without him, but encountered issues and have learned the errors of my prior ways.

I track each nute change by PPM, PH, ml/gal of each nute solution component, etc. and it is a great tool to learn the art of growing. I also jot down the daily PPM and PH levels (well, almost every day ... I promise I'll get it to daily) so I can see trends and such. I have a little excel document that I put together and am refining so I record the same parameters each time.

Hmmm, now that I mentioned it I should finish the form and perhaps, oh maybe, post it up to CannCom for others to use?
