Everything is good. Switched them to a 19:6 light schedule with the dark period during the hottest point in the day. These are growing in a small shed so ambient temperatures play an important role and light and exhaust cycles have to be adjusted to maximize physical variables.
Lights are set to 30-40% and around 30 inches above the soil. Humidifier keeps RH around 55%.
They seem to be doing really well and are taking off.
