i would also put month on top right so when you have it in a binder you can see by just flicking corner maybe use left side to list strains and # of plants such #lights etc
Just a few more ideas not that you need to use them :P
For PH section i would just leave a blank line to write ph down cause nice to have true ph as 6.2 or 5.8 etc
maybe add a little box in corner of each day to mark what day it is.
Also maybe section for temp?
Looks good though. +rep
How long did you veg for? Roots grow slow when flowing, you want to make sure you have good root mass before you flower.
Have you been checking ph and ppm? maybe you have salt build up in your soil? plants look a little stretched, maybe put the light a bit closer.
light doesn't hurt your shrooms or the mycilum. You want to use a non transparent tub to prevent side pinning. A black garbage bag works great as a liner.
Side pinning is when the mushroom starts to grow on sides of your substrate and they get all squished up against the side of the tub.
I got Jorge's book, Buds for less, and the garden saver online the other day.
Waiting for the new edition of the cannabis grow bible to come out in next month or so.
