Just switched to 12-12 light as pistils emerged on the two Solomatics. Overall happy with the progress and nutrients. No visible issues so far.
Hopefully, the photoperiod change is okay for the Special Queen. She went into soil five days later than the rest and isn't an autoflower. Fingers crossed, because otherwise she's looking very vibrant.
@raptor65,
Thanks for the well wishes! I topped one of the Solomatic babies this morning, as I have seen pretty low yields from them in other diaries. The others I'll let go without any interventions except problem resolution (hopefully won't be needed).
