The plant family is completely back to health, ignoring the older leaves which caught the brunt of a lack of water (I'm sorry, plant friends!). From this point until flowering time I just need to keep watering them, training them to grow with a flat canopy (instead of in the tree shape cannabis is most inclined to grow), gradually increase the fertilizer dose, and wait until they're about half the final height I'd want to aim for. At that point I'll switch their light over from 18h/day to 12h/day, and that'll trigger them to grow a final stretch before flowering.
