Thank you @litguru!

The closest to harvest are the small clones that I'm taking macro shots of.
I'm only expecting a few grams off of each of those two plants. They have maybe two weeks left at this point.

The larger plants are a few weeks behind them in flowering.

Ultimately the trichome coloration from milky to amber color will dictate when the plants come down, now that I have the ability to inspect this vital aspect.

A 50% degradation from milky to amber trichomes is commonly agreed upon as the best time to harvest, because psychoactive compounds are well maintained, and the medicinal cannabidiol (amber color trichomes) is also present, making for a nice balanced quality effect.
