Why she looking so sad?

I have to agree that she looks just fine - all she's doing is straining for light! If you have to keep her in the window, I would do two things... I would set her on a large saucer with pebbles in it and fill that up with water to give her the humidity she needs... and then I would turn her a couple times a day so she isn't growing so sideways. If you start that now, turn her so she's leaning into the room... she'll soon start reaching back to the window for her light... once she is more upright, keep turning her around and around during the day so she stays upright! Good luck! She actually looks good, just needs to get her light!

She's absolutely fine and healthy she's just slanted to that side because that's where the sun hits so that's where she's going to go just turn her around so back side can hit sun and she'll straighten up. Best of luck 👍

She is sad. If it’s not too much water, it’s environment. Your RH isn’t high, your temps are too low, and she isn’t getting enough light.

companies promise a lot... be wary of them without an overabundance of evidence from a different source(s). just to make sure irrigation habits are good. You should get a little runoff in soil to ensure you have fully saturated the substrate. i see you cut your soil with 50% perlite? that'll be great for the ffof. It'll still be full of nutes for 4-6 weeks or more. it's pretty hot soil. so, in general allow top 1" to dry, give or take -- even better to familiarize yourself with the weight of a 'dry' pot... it'll be a more consistent point, if you do. you'll need same volume to get that weight back up + a little runoff to be safe. with a 50% perlite mix, it'll be virtually impossible to overwater your plant. if you ran 3, maybe 4x as much water as necessary, it might cause a droop at some point, but even that should clear up quickly. if you try more frequent irrigaitons at 50% or 75% of original weight, just make sure to enact some preventative measures for pests.
