Science, logical, and farmers clearly agree. It's either defence (e.g. production of 'resin', essential oils etc.) or growth (e.g. yield). But it doesn't matter if it's a 'molecular' attack (in the end, it all comes down to molecules no matter what) or any other stress (incl. temperature, drought, feeding insects, you name it) which triggers an immune/growth response. What matters is the response chosen by the plant: not every trigger induces the production of the desired defence molecules (THC). It also doesn't really matter if it's during the bulking phase or before. Yield-wise, there is less to lose if you stress the plant once fully grown out cause obviously, it doesn't grow any more anyway

What all that has to do with Terpenez and it's organically derived ingredients I do not know. Some use defined chemicals (PGRs), others apply loosely defined products of natural origin (biostimulants) or micro-organisms, and yet again others brew stuff from stuff or whatever. Applied to plants, they all converge to the same few bottlenecks in the plant's signalling cascade. It's about the same as if you'd take either an Aspirin, lyophilised meadowsweet extract, or all organic willow bark tea against your headache.
