Yes, end of life.
Pot is a bit small, 15 litres much better.
120 watt light really is on the "not enough" list too.
Having the fan blowing directly on the plant is not ideal either, try to have it blowing between the light and the plant, just so the top of the plant has slight movement.
Please read the answer I gave MDMA99 (yellow leaves?) on a very similar question to yours, a few questions up the page to your question, it contains information that you may find useful.
