The one in peril, she may have lesser roots. If you are organic, a fish water feeding and a myco drench may fix her right up in about a week. VPD really just matches the roots to the shoots without light poisoning her. It syncs her intake to her rate of photosynthesis.Well, funny....I couldn't compute when I was in pain this morning. But now that I'm zooted, this makes sense. LOL
Thanks again! I think I may have a plant with some kind of deficiency going on, we will use this to dial in what's up.
This is going to be a nice learning experience.
Looks like my VPD calculation for mid flower is okay at 1.4ish.
But that one plant....I'll work on it tomorrow when I can get the refractometer tests done.
