That’s good to hear.From my understanding, it's exposure to the range allowing them to uptake the nutrients. To go beyond that explanation- couldn't tell you. I've only done this a few times, and can tell you what's worked with me, and what I've read.
There’s certainly a lot of info on the various cannabis sites but I’d like to find a reference for this. Somebody in some lab somewhere has looked into this. Time to search the bookstore.
[edit]
Blinding flash of the obvious - for some reason, the plants are doing something to raise pH and keep it at a certain level. That tells my little brain that either they don’t want/need the nutes that are available at the lower levels and/or they want the goodies that they get from the higher pH values. If the latter is the case, then we should see pH drop by adding the nutes that are taken up only at or in significantly higher levels when pH is at 6.3. I don’t have a nute chart available at the moment but, if there’s a note that fits that description, that could be why the plants are going to 6.3.
On the other hand, I could just buy a book and remove all doubt!
