Me too.
3 or 4 times daily I note the max/min and current temp & RH (I always wipe the info when returning the hygrometer to the tent)
Every evening I take the pH and EC levels and note down those.
If the temp or RH is an unusual level I try to explain why.
Eg "High temp and RH 90%+ - I forgot to increase fan speed after the lights went back on"
or "Low temp - left desk fans and inline on full power for an hours of lights off".

My printer will print calendars with large blocks, plenty of space for writing notes. I love using calendars, it's easy to keep track of things and I can look back at what I did. I also use the "Notes" app on my ipad.
