Ok thanks for your honesty. Do you think I should buy some flowering food? Do you have any names in mind ?
@TheKushie But it will not receive any sun then. Isn't it a problem?
TheKushi is suggesting a clear bag, sort of like a mini greenhouse, the light will pass through, I have no experience doing this though and would worry about poor airflow and high humidity causing problems with fungus.
I would highly recommend you get a dry fertilizer, I'm not in your area so I can't suggest any brands. What I use (in Canada) is Gaia Greens Power Bloom 2-8-4 for flowering combined with a bit of
Gaia Green All Purpose 4-4-4 (about 75% 2-8-4, 25% of 4-4-4). I use about 6 TBSP for my 5 gallon pots and that will feed the plant for 3-4 weeks.
GAIA GREEN Power Bloom is a high phosphate fertilizer specifically formulated to support prolific flowering and fruiting. As a result,
GAIA GREEN Power Bloom is our best fertilizer for root development and for all flowering and fruiting plants. ORGANIC
GAIA GREEN Power Bloom is approved for use...

I would recommend you find something local from a garden centre, look for something that is either organic, or slow release. Sprinkle the amount suggested by the product on the ground around your plant (approximately 2 to 3 inches from the stem) and water it in. This should be enough food for your plant for the rest of it's life.
Something to note, your plant looks like it wants more nitrogen right now, you don't want too much during flower though, you should look at the fertilizer you buy and if its organic it should tell you how much of the nitrogen is immediately available, for example the
Gaia Green 2-8-4 has 0.5% immediately available nitrogen, and 1.5% slow release, the 4-4-4 has 3% immediately available and 1% slow release. You will need a fertilizer that has at least some of the nitrogen immediately available otherwise it will take too long for your plant to get the nitrogen it wants right now.
