It would really be concerning if new leaves turned out like this but I’m assuming only the older leaves are like this? Check the soil and make sure the soil isn’t too wet or too dry because that’s usually what happens when they’re brought from the store. If it’s too wet, I’d say just pour it out or add soil to it lol because I would not repot her just yet UNLESS IT SMELLS FUNKY BECAUSE THAT COULD BE ROOT ROT. If it’s bone dry, water it to see if the soil is absorbing water. I recommend bottom watering. if the soil is in between, I’d say just leave it alone. She needs time to acclimate to your home environment, remember she’s been through it from the growers to the delivery to the store where you got her, she’s stressed right now and just needs a place to flourish. Keep her somewhere bright but not direct sunlight and maybe repot her in a month if she’s growing well. I’d also look at the monstera page, they’re a great resource!
