They've grown quite a bit, soon I will start applying LST in order to get the most out of these beautiful little ladies.
@Gamemaniaks hooked me up with a one-time root growth mix and they've been at a steady pace ever since.
The LED seemed to be too close to the canopy, however, and this has caused some burn on some of the older leaves.
I've since raised the LED to be 19-20cm above the canopy and have changed the light cycle to have the LED running for 24/7.
They've been receiving consistent watering now, essentially by checking the moisture levels with my meter.
I've also misted them to heighten the moisture level when it fell on the lower end.
