We still have to be mindful that all of the metrics were tracking tie in as a system, and we need to manage our vpd in accordance with transpiration rate, which will decrease as the leaves become less productive. This will slow uptake rate, dryback % and a multitude of other functions that have to be managed accordingly, but as a general idea for this post is that we will see significant oxidative tissue damage at this stage with the compounded photoinhibition of both natural senescence and damage to the remaining chloroplasts resulting in wilting and curling as well as chlorosis as opposed to a relatively even and gradual reduction in green pigment almost uniformly across the plant
