My plants have grown a lot lately.
The paprika, tomato and chilli are getting so big that they almost cover each other and now I´m worried that they won´t get enough sunlight. I am considering cutting off the tops of the plants (to make them shorter and more stable) but on some online gardening communities they say that that is a bad idea because it makes the harvest late. But is that a problem? The windowfarm is indoors and I don´t mind waiting.Are there other reasons not to?

Do or don´t? Any suggestions?
