It is covered early on in the thread, at least as far as the grand scheme of things is considered since she brought up that watering during flowering was done differently than done when in the vegetating stage. The link below has a message that I posted which lists the times she discussed the differences.After many years once again I am growing for myself again. I got back to your thread and after reading it now I wonder if "when to water" applies to both vegetative and flowering stages as well.
Follow that link and find the msg I posted. It will have about 15 links to her msgs. It is important to keep in mind is that each link looks the same but each will point to a different msg. The first one in the list points to the Addendum and each of the following links goes to different but still important messages that explain the why or how of the watering during flowering .
