hey there Mr.Joint , the downward pointing leafs are a symptom of root zone issues. And i know you dont want to hear this but these are due to overwatering. you can tell from the puffy space between the veins of the leafs as well as the wrinkles. The overwatering basically caused a minor water mold issue at the roots. Probably what happened is that the soil in the middle of the pot got a bit compacted and is retaining water a bit more causing chronic humidity. try decompacting the soil by hugging your pot, then follow and even stricted wet dry cycle. you probably dont need this but try the lifting pot method to never overwater again
