Dreaming Big 2.0

So out of nowhere I noticed that she's reverted back to 3 leaf sets. Overall looks healthy but all new growth accept the main colas have 3 leaf sets established and forming. Cola has 4 leaf sets. The 5s are old growth previous to supercropping.
I read this can be due to change in light schedule which I have been at 24/0 for over a month since we got it. We did just turn them up last week from 40% to 50% for a few days and settled at 60% which gave us 40 DLI for that plant is week 5-6.
Has anyone experienced this. I wouldn't have even noticed it if I didn't take a dozen leaves off to open up light to bud site development areas.

It still looks healthy so I'm not overly concerned.

It sat at 58% most of the day yesterday. We moved the humidifier and dehumidifier around. But our temps are dropping again which is pulling us out of the ideal VPD range. I'll head back over there this morning and try to fix that.

Red line, 5:45AM "Steve" moves the dehumidifier to the center of the current grow area. He also turned the humidifier knob down from 75% to 25%. (Not smart humidifier, it's a stupid one with no control or sensors for RH.)

Yellow line, 10:35AM I enter with a second box fan and a heater with auto settings. Heater gets set to 71°F and I waited for it to turn off before leaving to verify autonomy. Kicks back off at 73° near the heater which is on the opposite side of the grow room from the plants. I refilled the humidifier and turned it up to 50%.

Heater has kicked back on twice since I left. Should be back on again very soon. Each time it drops the humidity down about 5-10% but still keeps the VPD within range for veg.
