how do i know when to put my plant on 12/12

Zigzag, or alternating, nodes are the most reliable indicator that the plant has decided it is ready to move to its next life stage.

Cool! That means this one's ready, cuz since this morning, it's defo doing the zig-zag

The full moon... ur... are you growing outside?

Nope. But I've always used moon cycles as change points. No scientific reasoning behind it; it just "feels right".

I would not make 2 light changes. Irregular photoperiod can trigger herms, so the evener the light regimen, the better.

I do the pre-bud cycle (18/6) after the 24/7 to stimulate root growth. I'm under the assumption that a dark period is beneficial for root system development. Is this incorrect?

This light change also simulates the end of mid-summer above the arctic circle. I try to mimic a complete season in a short time, swapping & cycling between different spectra bulbs - easy to do w/CFTs - and doing the 24/7 to 18/6 (one week) to 12/12 (however long) to 10/14 (last week) to 38 hours darkness thing.

To date, I have not had any hermies. But I'm sure I'll run into one sooner or later, it's gotta happen eventually, right?
