Tapering PPFD and watering at the end?

@DirtySlowToes

Not to get a jump on drying, but to stress the plant into last ditch efforts to reproduce(increase terpene/cannabinoid production). No idea the truth to that one.

This is true, I posted a paper here somewhere.
I think it is here.

Different types of plant stress, 1:(LAR), 2:(SAR), 3:(SGS), 4:(ISR), 5:(SWR)

Induced Resistance There is a diverse array of signals that stimulate IR. IR is a sensitization process that primes the plant for more rapid deployment of defenses. When integrated into good agricultural practices, IR can both enhance plant productivity and resistance to disease. Has energetic costs Types of induced resistance Local acquired resistance (LAR) Systemic acquired resistance (SAR) Systemic gene silencing (SGS) Induced systemic resistance (ISR) Systemic wounding response (SWR) S…

I found this too.

Severe drought significantly reduces floral hemp (Cannabis sativa L.) yield...

Research performed in high-THC cannabis has shown that late and mild water stress can increase THC levels (Caplan et al., 2019). It is hypothesized that secondary metabolites are produced as a defense mechanism against stresses such as herbivory attacks (Jackson et al., 2021).

use DLI as the proper target.

Now I don’t mean to overwhelm you but there are things to consider like midday depression.
Plants are exposed to high light intensity, high leaf temperatures and high air-to-leaf water vapor pressure deficit (ALVPD) during the day . These environmental stresses cause stomatal closure and photoinhibitory damage, leading to midday depression of photosynthesis.
