Yet another case of people racing through questions for points. This is not normal! It’s obvious to me that she is overwatered. Plant is droopy and leaves are swollen from being water logged forcing them to curl down like that. An overwatered plant will stop assimilating nutrients and all kinds of deficiencies will pop up. You need to let it dry out as quick as you can by increasing temp, increase ventilation, decrease RH, carefully poke air holes in medium and or let plant sit outside of its pot. Let it dry out completely before watering again at a reduced rate. I know this will help! Cheers 🍻
