Custard Apple - Looking for some tips and help for my plant

[Tropical89]

Hello! I was hoping someone can help me, I’ve had this little plant grown from seed for about 9-10 months now and the leafs are curling and it doesn’t look very healthy, anyone have any tips?

Does it need a bigger pot? Fertiliser? Lack of water?

Any help would be appreciated!

From the image it looked like it needs more water. I can't tell clearly though.

Looks good to me, the curly leaves might be from heating/dry air.

I think it had too much water in winter.I have a small one that has the same issue when growing new leaves ( it lost all the leaves in winter).
What i did was to squeeze the pot until somme cracks formed in the soil so that air can get to the roots and ive also feed somme nitrogen rich fertiliser.
These are drought hardy plants that dont like being waterlogged especially in winter.
