Jackfruit Seedlings Bottom Leaves Turning Brown Despite Repotting In Fresh Soil And Regular Watering

Question

Hello, My 7-month old jackfruit seedlings were growing fine until about two months ago. They are all developing browning of the leaves, starting with the bottom ones and progressing to the upwards leaves until the plant dies completely. I am watering them daily and regularly, applied neem oil (though I cannot see any signs of pests), repotted them in fresh soil and bigger pots, and now have switched to filtered water instead of tap water to water them, but they do not seem to be recovering well. What do you think is the problem?! Thanks for your help!

I notice that the soil doesn't, quite, look like your typical potting soil. Likely, this is the problem, along with overwatering.

Check your soil for nutrient deficiencies, and add nutrients according to the test, or repot into a potting soil designed for fruit trees for a more simple solution.
