My jackfruit plant most bottom leaf is starting to droop downwards. It started with a slight brown and yellow colour of the inner
leaf and then slowly started to droop downwards.... i have been trying to find out what is wrong with it but i do not know and i a m afraid my plant will die. It has 4 leaves now i grew it from seed in a pot. Does anyone know what is wrong with my plant and how i help my plant?

There appears to be a few different issues here. I am seeing a magnesium deficiency, but I think this might have more to do with the pH of the soil. But I even think this might have something to do with overwatering.
You should tip the pot on its side just a little, and see if you notice any smells coming from it. If it smell s like sulfur then there are sulfur reducing bacteria present. This will make the pH of the soil EXTREMELY acidic causing the symptoms that you are seeing.
I would recommend removing this and starting with fresh soil designed for fruit or citrus. This will be a much lighter mix and will let the plant dry out a bit. between watering.
