please dont chop them down based on that stupid advice. Yes, they will turn under cfl. It might take a bit longer, but they got this far didn't they? No reason that they will not finish too. Just be patient. You are doing exactly the right thing, waiting.

Next time, try a bit more light and see how it changes things. Having seen the before and after, you will learn a lot!

Good luck, and enjoy your harvest when it happens... but please dont waste all this time because of one person's bad advice.
