I would advise not to remove any healthy green leaves at all. They are the only source of energy production that makes your plant grow.
For a more detailed explanation of why I recommend not removing any healthy green leaves and only removing yellow leaves, please read the answer I gave to "Basement grow 05"/ "Early flower", a few questions beneath yours on this very page, to a very similar question that he/she asked about this exact same topic. Hope this helps,.... Organoman.
