Update 9.12:
Forgot to update here! The height of the plants really exploded, especially one of them, which is now way too close to the LEDs. I’ve had to bend the tallest colas down using garden wire. For the next run, I definitely want to make better use of the ScrOG net to avoid this situation.
That said, all the plants are looking healthy and developing well—even the smaller one has caught up a little bit. This run has already taught me why working with a mother plant and clones would be preferable in the future.
