Is this drooping of the leaves concerning?

High Khando, this drooping does show the lack of oxygen at the roots. You can prevent this issue by only watering at the outside of the pot and not too close to the plant. When you do this the plant has enough water at the outside of the pot and enough oxygen at the center of the pot. This will solve the drooping. Happy Growing Buddy! 💚

This looks like they have enough water, make sure not to water too much as the roots probably didn't develop in a big pot and might just create pokets of water in the soil. My plants are usually drooping before lights turn off and a bit after lights go on. And during the middle of the day the leaves are stretching out more, so maybe check at different times of the day. They do look healthy, happy growing 🌱

Think you are lacking humidity in air. Plant looks like well or even slightly overwatered, but growing in low humidity. At least mine looked very similar in such conditions.
