Very bottom leaf set curling all of a sudden

Can anyone tell me what’s going on here? It’s only the very bottom set. She is 4 weeks today. Thanks a bunch

temps have been 79-81, RH around 50%

What do you have to the left of the pot?
Could be affecting the lower leaves.

shoebox on one side for height of the others, humidifier on the right, also there is a bit too much space for soil in the pot, could they not be getting air flow? Can I just cut em?

Perhaps the humidifier is too strong right next to the pot on the floor.
You can cut em but they’re not hurting anything.
I wouldn’t worry about it.

thanks @drsaltzman

You're better off trimming all that lower foliage to allow better airflow and easy access for watering.

trimmed just the bottom ones, they were soaked after watering and just looked rough…maybe I’ll just cut the lip off of the pot it’s in for airflow, rearranged the tent a little as well. Pot was super light too…I did not take into acct the increasing rate she would be drinking at as she grows. first grow, I’ll take any feedback/advice…thanks all for the help
