I would blame your growmedium// your feeding.... but iam not havingg much informations
but to me the girl looks hungry,,, so either the PH is wrong, or your feedings with a wrong ph or to low
these markings are lockout scars, it shows that the plant had PH swings
so yes add to your feeding calmag++Nitrogen
water more frequently, the airpots are drying out very much, try to wwater daily, keep humidity high ( 75 Perceent)
always feed into moist medium
and if i have more information to medium and feeding i can diagnose better
