KH i dont now.The most strange leaves.... please help !!!

hm. I would bet that it was because your humidity was so high.. and your temp was a bit high (and I'm a bit high). Once leaf damage is done, changing your growing conditions won't repair it. That damage will likely be there forever. look at your new growth. if that looks healthy, your plant is fine. If not, then you have other problems than temp and humidity.

Thhats crazy lookin. Never seen that but seems like it could be from heat. Don't think high humidity will do that but I could be wrong.

Maybe nobody knows what is dhis shit. I check everywher and nothing !!!!!!!!!!!!!!!!!

Maybe its genetics, just how that plant grows although could be wrong.

Does seem to look like there is something affecting it though..

Its ok if i cut some of this leaves ?
