Why are these leafs behaving like this

As u can seen in picture the 2 node is touching the earth . They were dry and droping , but when this happens after a few hours of watering they go back to positision , but in this case they stayed the same after watering and other leafs reacted normaly becoming erected .

What is happening to this plant , its the only one out of 4 doing this , the 2nd node just doesnt go up and is touching the earth:

Ps: humidity has been extremly low at 25% level

Temperature in the room?

25C / 77 F

Put the temp probe on the floor under the pot and see what’s the temp. Probably too cold and too dry. Purple stems= too cold (maybe)

Way too cold, temps with the lights off the temps should never be less than 20c. You may want to put your tent on top of rigid foam insulation, under my tent I have 2" thick blue foam sheets, this really helps to keep the drafts out and heat in.

Also, plants in veg will struggle with really low humidity, I use a $40 evaporative humidifier from rite aid that keeps the tent humidity between 55% - 65%, the growth will be much faster and healthier in this range.

Yes too cold and dry. How does it get so cold at night? Maybe switch your ‘day’ and ‘night’ so that the lights are off at the warm part of the day.
