Mogra buds not opening | Container gardening | Commercial Hydroponics farming in India

Hi,

I have 2 jasmine plants, grand duke of tuscany (butt morga) and belle of india elongated and there a few problems with them

For grand duke:

1.the buds do not open (it been over 6 weeks ) and they drop off.

2. the plant does not have many branches (just two) and seems to have stopped growing, however there are many leaves and they are green

For belle of india:

1. the buds fall of

2. the leaves at the bottom seem to be dried out and fall off easily

With both the plants the plants flowers are not very fragrant.

Some more info:

I have planted them  in container, on west side window with a lot of sunshine, i water them every morning and I live in mumbai.

I am very new to gardening and plants so I would like to know what can I do to make the plants come alive and bloom.

Thanks,

J
