I am NOT an expert, but when I used to grow aquatic aroids, they used to suffer "leaf burn'', and I was told that the man-made granular AND some liquid fertilizers which contain ''salts'' were the main cause of this problem. I was given some liquid fertilizers with a low-salt content, and advised to use them in a weak mix more frequently, and to allow rain to 'flush'' the soil as often as possible, I also used OLD cow manure and WEAK mixes of fish emulsion fertilizer, this certainly improved the leaf burn situation. Perhaps you need to reduce the amount of fertilizer you use?
I hope that this may work for you.

Subject: Re: [Aroid-l] Is this the symptom of overwatered Amorphophallus?
Thanks you for the responses. Let's see the answers:
- Sun burning and "peeling" - what means a type of mechanical damage (As I am correct)
- Over fertilization.
Because all my plants are inside the flat and none of them are in front of the window, the sun burst isn't my problem. As I know there was no mechanical damage, too.
But I fertalized my plants a lot, so it seems to be the real problem.
Thank you again Agoston and Scott!

This necrosis and burning of the edges of the leaf tissue is
typically a symptom of over fertilization.
