I agree 100% about "change my mind".
For years, I've run pH at 5.8 because it's "optimal". Bugbee recently discussed problems with iron uptake if pH gets really low (5.0±) so they run their grows at 6.0. No argument from me, per photo.

Do you have a link to that podcast? I'd like to hear what he has to say.
Westmoreland did a video in 2021 in which he briefly talked about temperature and cannabanoids but nary a peep about it from Bugbee until late last year. He did an interview and said that research was showing that "temperature would be as important as PPFD" (not a direct quote). Looking back at that statement, it looks like he was doing a little promo work for Westmoreland. He did a couple of videos early this year sharing some of his PhD research. An excellent hour of cannabis growing advice.
But dropping PPFD is surprising - why cut back on the plants' ability to make food?
Heh, that's why we have the pointy-headed guys, right?
