If new growth at the top is still coming in normal-sized and dark green, you are fine. If new leaves come in small and pale, that is real light starvation and you should act rather than wait.

A plastic pot is fine but check it actually has open drainage holes and is not sitting in a cover pot with 2cm of water in the bottom. I have found the second one more times than I would like to admit, in my own home.
