Needs Help for my Plant

[asif23]

AOA, everybody. I have this plant since quite a long time (pic attached) do not know the name. But the problem is that its leaves started to curl and die after they are little bit old and the plant size remains the same. I tries pesticides many types, changed the pot mix, moved the plant to shade/sunlight. I have been trying since a year but no luck. Would appreciate anybody's valuable suggestions especially Izhar Bahi's.
Thanks in Advance for your input.
Regards Asif.

It is a sign of stress which could be due to improper exposure.watering, fertilizer etc. I think in your case it might be over care thus over watering and fertilization as apparent from soil color and the npk granules

Have you tried putting it in a sheltered spot that has plenty of daylight but no direct sunlight. increasing the humidity level around the plant by placing maybe some large and small stones that you can lay onto a tray of water and then forgetting about it. Only watering it when the first inch or so of compost is dry to your dipped finger. It should perk up then

What is this plant ? Aglaonema ? if yes then it needs full protection from sun...infact it will do better indoors.
