Hi Gala -

It may help in getting more responses if you provide additional detail about your growing conditions:

What size container is the plant in?

It appears the plant may be inside? Do you ever place it outside to get more sunlight?

If it is only inside how many hours of sunlight does it get per day?

What type of soil mix is it currently in?

What type of fertilizer do you use and how often do you fertilize?

Hopefully, the answers to these questions will get things going.

Good luck!

Brian
